Abstract The effect of CdS content on the photo-induced improvement of hydrogen evolution reaction activity of the Pt/CdS electrocatalyst was investigated. Although the electrons transferred from CdS to Pt in the Pt/CdS electrocatalyst increased with the CdS content under illumination, the electrochemical active surface area of the Pt/CdS electrocatalyst decreased with the CdS content, resulting that the photo-induced improvement of hydrogen evolution reaction activity of the Pt/CdS electrocatalyst decreased with the CdS content.

光改进 Pt/CdS 电催化剂的析氢反应活性

摘要 研究了CdS含量对光致Pt/CdS电催化剂析氢反应活性提高的影响。虽然在光照下 Pt/CdS 电催化剂中从 CdS 转移到 Pt 的电子随着 CdS 含量的增加而增加，但 Pt/CdS 电催化剂的电化学活性表面积随着 CdS 含量的增加而减少，导致析氢反应的光诱导改善Pt/CdS 电催化剂的活性随着 CdS 含量的增加而降低。
