Photocatalysts comprising intimately interfaced photoabsorbers and co-promoters for the enhanced photocatalytic efficiency have gained much attention. In this paper,efficient promoters of NiS decorated MoS_(2) nanosheets (MoS_(2)/NiS) coupled with Zn_(x)Cd_(1−x)S nanorods have been prepared through a convenient hydrothermal method. The as-achieved Zn_(0.2)Cd_(0.8)S/MoS_(2)/NiS nanohybrids exhibited a high solar H_(2) evolution activity with a rate of 41.29 mmol gcat^(−1) h^(−1) and the apparent quantum efficiency of 19% at a wavelength of 435 nm. The result represents one of the most active photocatalysts with noble-metal-free co-catalysts. The synergetic effects of MoS_(2) and NiS are responsible for the enhanced photocatalytic activity,and the presence of NiS further promotes the photo-induced electron-transfer from Zn_(0.2)Cd_(0.8)S to MoS_(2). This work opens an avenue for the design of efficient co-catalysts towards the enhancement of photocatalytic performance.展开更多

文摘Solid oxide electrolysis cells(SOECs),displaying high current density and energy efficiency,have been proven to be an effective technique to electrochemically reduce CO_(2)into CO.However,the insufficiency of cathode activity and stability is a tricky problem to be addressed for SOECs.Hence,it is urgent to develop suitable cathode materials with excellent catalytic activity and stability for further practical application of SOECs.Herein,a reduced perovskite oxide,Pr_(0.35)Sr_(0.6)Fe_(0.7)Cu_(0.2)Mo_(0.1)O_(3-δ)(PSFCM0.35),is developed as SOECs cathode to electrolyze CO_(2).After reduction in 10%H_(2)/Ar,Cu and Fe nanoparticles are exsolved from the PSFCM0.35 lattice,resulting in a phase transformation from cubic perovskite to Ruddlesden-Popper(RP)perovskite with more oxygen vacancies.The exsolved metal nanoparticles are tightly attached to the perovskite substrate and afford more active sites to accelerate CO_(2)adsorption and dissociation on the cathode surface.The significantly strengthened CO_(2)adsorption capacity obtained after reduction is demonstrated by in situ Fourier transform-infrared(FT-IR)spectra.Symmetric cells with the reduced PSFCM0.35(R-PSFCM0.35)electrode exhibit a low polarization resistance of 0.43Ωcm^(2)at 850℃.Single electrolysis cells with the R-PSFCM0.35 cathode display an outstanding current density of 2947 mA cm^(-2)at 850℃and 1.6 V.In addition,the catalytic stability of the R-PSFCM0.35 cathode is also proved by operating at 800℃with an applied constant current density of 600 mA cm^(-2)for 100 h.

文摘The oxidation reaction of manganese(Ⅱ)acetate tetrahydrate with terbium(Ⅲ)nitrate hexahydrate in acetonitrile in the presence of 4-(methylthio)benzoic acid(Hbza·SMe)afforded a polynuclear[Mn_(11)^(Ⅲ)-Tb_(4)^(Ⅲ)O_(9)(OH)_(5)(bza·SMe)_(18)(NO_(3))_(2)(H_(2)O)_(6)(OMe)_(2)]complex(1)with a{Mn_(5)Tb_(2)O_(6)}-bridged double-{TbMn_(3)O_(4)}-cubane structure.This antiferromagnetically coupled,neutral molecule is decorated in the periphery with structurally exposed thioether groups which can be used as anchors to metallic surfaces.Compound 1 is potentially a single-molecule magnet(SMM),exhibiting slow relaxation of the magnetisation up to 3 K.While 1 is not thermally stable,the coordination cluster remains stable in various Lewis base-type organic solvents like THF and acetone.

文摘In this work,NiFe-layered double hydroxide(NFL)nanosheet arrays loaded with NiFe nanoparticles(NiFe NPs)were prepared via a one-step partial reduction strategy and MoS_(2)/NiFe NPs/NFL/CC with sandwich structure was fabricated by integrating caterpillar-like few-layer MoS_(2)nanosheets into NiFe NP interlayers over NFL nanosheets.Benefitting from the highly exposed active sites on MoS_(2)layers,the crystal structure and excellent electronic properties of metal alloys as well as the optimized heterojunction structure,MoS_(2)/NiFe NPs/NFL/CC exhibited good electrocatalytic water splitting performance.The overpotentials for oxygen evolution reactions(OERs)and hydrogen evolution reactions(HERs)are 118 mV(η_(10))and 212 mV(η_(10)),respectively,in 1.0 M KOH electrolyte.Due to the synergistic effects of interface engineering approaches,the overall water splitting device with MoS_(2)/NiFe NPs/NFL/CC as both electrodes exhibited a low voltage of 1.54 V at 10 mA cm^(−2) and outstanding long-term stability for over 30 h.This interface engineering approach paves the way for the further investigation of NiFe-based electrocatalysts.

文摘Facilitating charge separation as well as surface redox reactions is central to improve semiconductor catalyzed solar hydrogen generation. Photocatalysts comprising intimately interfaced photoabsorbers and co-promoters for the enhanced photocatalytic efficiency have gained much attention. In this paper,efficient promoters of NiS decorated MoS_(2) nanosheets (MoS_(2)/NiS) coupled with Zn_(x)Cd_(1−x)S nanorods have been prepared through a convenient hydrothermal method. The as-achieved Zn_(0.2)Cd_(0.8)S/MoS_(2)/NiS nanohybrids exhibited a high solar H_(2) evolution activity with a rate of 41.29 mmol gcat^(−1) h^(−1) and the apparent quantum efficiency of 19% at a wavelength of 435 nm. The result represents one of the most active photocatalysts with noble-metal-free co-catalysts. The synergetic effects of MoS_(2) and NiS are responsible for the enhanced photocatalytic activity,and the presence of NiS further promotes the photo-induced electron-transfer from Zn_(0.2)Cd_(0.8)S to MoS_(2). This work opens an avenue for the design of efficient co-catalysts towards the enhancement of photocatalytic performance.

文摘Bismuth(Bi)-based nanomaterials are considered as promising electrocatalysts for the electrocatalytic CO_(2) reduction reaction(CO_(2)RR),but it is still challenging to achieve high current density and selectivity in a wide potential window.Herein,Cu-decorated Bi/Bi_(2)O_(3) nanofoam(P-Cu-BiNF)with a 3D porous network structure was prepared for the first time via a simple fast-reduction method.Characterizations indicate that the introduction of Cu can significantly regulate the microstructure and electronic states of Bi/Bi_(2)O_(3).Consequently,the as-prepared P-Cu-BiNF exhibits excellent electrocatalytic performance toward the CO_(2)RR.Remarkably,the faradaic efficiency of formate production can exceed 90% in a wide potential range from -0.78 to -1.08 V.Meanwhile,it can also deliver a high formate partial current density of up to 62.7 mA cm^(-2) at -1.18 V and long-term stability.This work provides a simple but effective way to synthesize advanced Bi-based materials with significantly improved electrocatalytic CO_(2)RR performance.

文摘Electrocatalytic N_(2)reduction is a sustainable alternative to the Haber-Bosch process for ambient NH_(3)synthesis,but it needs efficient and stable catalysts.Herein,a hybrid of TiO_(2)and juncus effusus-derived carbon microtubes with a three-dimensional cross-linked hollow tubular structure is proposed as an efficient electrocatalyst for N_(2)-to-NH_(3)conversion at ambient conditions.In 0.1 M Na_(2)SO_(4),this catalyst offers a large NH_(3)yield of 20.03µg h^(-1)mg_(cat.)^(-1)and a high faradaic efficiency of 10.76%at-0.50 V versus the reversible hydrogen electrode,with superior electrochemical and structural stability.

文摘We report herein an innovative design and synthesis of a novel multifunctional nanocatalyst for the transfer hydrogenation(TH)of nitroarenes and olefins using water as a hydrogen source and solvent.The presented nanocatalyst is composed of NiPd alloy nanoparticles(NPs)supported on reduced graphene oxide(rGO)decorated with metallic Al NPs(Al-rGO/NiPd).In the catalyst,metallic Al NPs serve as the sacrificing agent for hydrogen generation via the Al-H_(2)O reaction,NiPd NPs act as the catalyst for the transfer of the generated hydrogen to the unsaturated compounds,and rGO functions as both a support material and stabilizer for the NPs.Among all tested catalysts,Al-rGO/Ni_(40)Pd_(60)nanocatalysts are found to be the most efficient and selective catalysts in the presented TH of nitroarenes(14 examples)and olefins(14 examples)with yields reaching up to 99%under the optimized reaction conditions.Additionally,Al-rGO/Ni_(40)Pd_(60)nanocatalysts are recyclable catalysts in the TH reactions by catalyzing ten consecutive runs in the TH of nitrobenzene without a significant drop in their initial catalytic activity,which is the first example in this regard.Last but not least,the current transfer hydrogenation protocol provides selectivity for the reduction of only the-NO_(2)group of nitroarenes bearing iodo or bromo substituents on the same aromatic ring.This study is the first example of a TH protocol that employs an Al-modified nanomaterial serving as both a hydrogen generator and reusable catalyst in water without using any additional hydrogen source.

文摘In this paper,a novel electrochemical sensor based on a functionalized multi-walled carbon nanotube(f-MWCNT)decorated ruskin michelle-like zinc oxide(ZnO)nanocomposite for the determination of the environmental pollutant hydroquinone(HQ)is reported.We have followed a new aqueous solution method for the synthesis of ruskin michelle-like ZnO nanoparticles and they are characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),Raman spectroscopy,Fourier transform infrared(FT-IR)spectroscopy and UV visible spectroscopy.Cyclic voltammetry(CV),differential pulse voltammetry(DPV)and amperometric techniques are used for the electrochemical analysis of a f-MWCNT decorated ruskin michelle-like ZnO nanocomposite modified glassy carbon electrode(GCE).The fabricated f-MWCNT/ZnO GCE showcased excellent electrocatalytic activity in the determination of HQ and we obtained a sharp anodic and cathodic peak current at a low potential value of 0.11 V and 0.05 V,respectively.Efficient reproducibility and stability,anti-interference property and good repeatability,which are the traits of a good electrochemical sensor,are exhibited by the fabricated sensor.We have obtained a very low limit of detection(LOD)for the fabricated f-MWCNT/ZnO GCE of 0.02μM,a linear response in the range of 0.1-190μM and a sensitivity of 6.37μAμM^(-1)cm^(-2).These results obtained from the electrochemical analysis reveal the excellent performance of the f-MWCNT decorated ruskin michelle-like ZnO nanocomposite modified GCE in the effective determination of HQ.
