High-efficient inexpensive separation materials are critical to success. In this review, separation materials such as polymers and nanomaterials are summarized and compared. Combining the advantages of the adsorptive membranes and nanomaterials, organic–inorganic hybrid/blend membranes have been developed explosively. These hybrid/blend membranes have both the characteristics of high permeability, easy fabrication, good biocompatibility of adsorptive membranes, and characteristics of fast adsorption rate and high adsorption capacity of nanomaterials. The preparation and modification methodology of the separation materials is reviewed. For affinity separation materials, the relationship of ligand chemistry, ligand density and pores of the matrix is discussed. This paper also summarizes some interesting applications in separation materials for removal of bilirubin, endotoxin, toxic metal ions, cytokine, etc.展开更多
In this work,we propose a facile,fast and large-scale synthesis ofβ-Mo_(2)C catalysts(about 100 grams).The current approach uses a simple solid mixture of(NH_(4))_(6)Mo_(7)O_(24)·4H_(2)O and carbon nanotubes(CNT...In this work,we propose a facile,fast and large-scale synthesis ofβ-Mo_(2)C catalysts(about 100 grams).The current approach uses a simple solid mixture of(NH_(4))_(6)Mo_(7)O_(24)·4H_(2)O and carbon nanotubes(CNTs)as a precursor and employs a fast heating rate method without holding time.Moreover,there was no need for passivating the carbide products.A series ofβ-Mo_(2)C/CNT catalysts(denoted as MoC-5,-15,-30 and-60)were successfully prepared from the precursors with the Mo content ranging from 5 to 60 wt%and their catalytic activities for dry reforming of methane(DRM)were evaluated.CH_(4)-TPSR and CO_(2)-TPO over the fresh samples proved that the abilities of CH_(4)dissociation and oxidation resistance ofβ-Mo_(2)C were greatly enhanced by compositing with CNTs.It was also found that these abilities were dependent on the Mo content,the particle size and the interaction betweenβ-Mo_(2)C and CNTs.Among theseβ-Mo_(2)C/CNT catalysts,MoC-30 showed the best catalytic stability for DRM,attributed to its high activity for CH_(4)dissociation and high resistance to oxidation.Additionally,it is worth noting that the catalytic stability of monometallic MoC-30 was found to be superior to that of bimetallic Ni/β-Mo_(2)C(recently known to be an efficient non-noble metal catalyst for DRM).展开更多
