摘要
根据物理化学实验教学的需求,设计了一个单原子催化剂的合成及电催化分解水产氢物理化学综合实验。电催化水分解是当前的热点领域,本实验将其引入本校材料专业实验教学体系,以拓宽学生的科研视野。这不仅有助于学生掌握专业知识和实验仪器操作技能,还能进一步提升其创新思维和科研素养。该实验设计以典型的单原子电催化剂为例,先采用水热及氧化还原法,在碳纸导电基底上成功合成了Pt-Ni-CoP催化剂。利用X射线衍射(XRD)和扫描电子显微镜(SEM)等手段,对催化剂的晶体结构和微观形貌进行了系统表征。最终,采用电化学工作站对其电催化分解水产氢性能进行了系统测试。测试结果显示,Pt-Ni-CoP催化剂在10 mA·cm^(-2)的电流密度下,过电势仅为62 mV,并展现出卓越的稳定性。这些结果表明,该催化剂在电催化领域展现出巨大的应用价值。
According to the needs of physical chemistry experimental teaching,an integrated physical chemistry experiment has been developed,focusing on the synthesis of single-atom catalysts and their application in electrocatalytic water splitting for hydrogen production.The electrocatalytic water splitting represents a current hotspot in research.The experiment integrates it into the experimental teaching system of our university’s materials science program,aiming to broaden students’scientific research horizons.It aims to enhance students'innovative capabilities and research literacy while they acquire professional knowledge and gain hands-on experience with experimental instruments.The experimental design focuses on a representative single-atom electrocatalyst.Initially,the Pt-Ni-CoP catalyst was synthesized on a carbon paper conductive substrate using hydrothermal and redox techniques.Following synthesis,the catalyst was characterized through methods such as X-ray diffraction(XRD)and scanning electron microscopy(SEM).Finally,its electrocatalytic hydrogen production performance was evaluated using an electrochemical workstation.The results indicated that the Pt-Ni-CoP catalyst exhibited an overpotential of just 62 mV at a current density of 10 mA·cm^(-2) and demonstrated outstanding stability,highlighting its promising potential for applications in electrocatalysis.
