Abstract

In this communication, we present a new synthesis method for the fabrication of hybrid metal-CuS (M = Pt, FePt) nanocrystals (HNs). The metal-CuS HNs were investigated in photocatalytic hydrogen generation as effective co-catalysts on TiO. The Pt-CuS/TiO catalyst showed a higher hydrogen generation rate compared with a pure TiO catalyst. This enhancement is attributed to the synergistic effects between CuS and Pt, which significantly improve the light absorption ability and the charge separation activity.

摘要

在本通讯中，我们提出了一种用于制备混合金属 - 硫化铜（M = 铂、铁铂）纳米晶体（HNs）的新合成方法。对金属 - 硫化铜HNs作为TiO上有效的助催化剂用于光催化产氢进行了研究。与纯TiO催化剂相比，铂 - 硫化铜/TiO催化剂表现出更高的产氢速率。这种增强归因于硫化铜和铂之间的协同效应，其显著提高了光吸收能力和电荷分离活性。
