| 摘 要： | 将MoS2电催化剂担载在InP光阴极表面，提升了InP光阴极光电化学分解水产氢性能，确定了最优的MoS2电催化剂担载电量为15mC·cm-2；在担载前后，开启电势由-100mV移动至120mV；在-0.35VvsRHE时，电流密度由15mA·cm-2提升至43mA·cm-2。另外，通过改变入射光强和加入电子牺牲剂的方法进一步研究了MoS2担载InP光阴极产氢反应的限制步骤为光生电子与空穴在InP表面的复合。

| Abstract: | MoS2 as a co-catalyst was loaded on the surface of a p-InPphotocathode to improve the photoelectrochemical property. The optimum electrical quantity of MoS2 loading was 15 mC·cm-2. After the MoS2 loading, onset potential of an InPphotocathode was shifted from-100 mV to 120 mV, and current density was improved from 15 mA·cm-2 to 43 mA·cm-2 at -0.35 V vs RHE. Moreover,the limit step of a MoS2/InP photocathode for hydrogen evolution was investigated by controlling light intensity and adding electron sacrificial agent into the electrolyte. Recombination of the photogenerated electrons and holes was the limit step on a MoS2/InP photocathode for hydrogen evolution. |
