摘要
以硝酸钴、硝酸锌为主要原料,分别采用L-半胱氨酸和硫脲为硫源制备钴掺杂硫化锌,借助XRD、SEM、TEM等对其形貌及结构进行表征,并通过析氢实验探讨不同硫化方式对钴掺杂硫化锌电催化性能的影响。结果表明,以L-半胱氨酸硫化法制备的钴掺杂硫化锌催化剂结晶度高且具有更好的电催化析氢效果。
Based on cobalt nitrate and zinc nitrate,the cobalt-doped zinc sulfide materials were prepared by using L-cysteine and thiourea as sulfur sources,respectively. The morphology and microstructure of as-prepared samples were characterized by XRD,SEM and TEM. The effect of different sulfurization methods on the electrocatalysis of cobalt-doped zinc sulfide was investigated through hydrogen evolution experiments. The results show that the cobalt-doped zinc sulfide catalyst synthesized by L-cysteine sulfuration has high crystallinity and better electrocatalysis for hydrogen evolution.
