Abstract

Herein, we achieved successful synthesis of 2D Cu2S nanosheets (NS) with a thickness of 1.2 nm by a novel strategy. The key to obtain ultra-thin Cu2S NS was the use of a unique sulfur precursor which not only supplied sulfur in a controlled manner, but also directed the formation of a 2D structure. The as-prepared Cu2S NS were proved to be effective cocatalysts for photocatalytic hydrogen production. The H2 production rate of Cu2S NS/TiO2 reached 1430.4 μmol g(-1) h(-1), which was 4.9 times higher than that of TiO2.

摘要

在此，我们通过一种新策略成功合成了厚度为 1.2nm 的二维 Cu2S 纳米片（NS）。获得超薄 Cu2S NS 的关键是使用独特的硫前体，它不仅以可控的方式提供硫，而且还指导二维结构的形成。所制备的 Cu2S NS 被证明是光催化制氢的有效助催化剂。Cu2S NS/TiO2 的 H2 生成速率达到 1430.4 μmol g(-1) h(-1)，是 TiO2 的 4.9 倍。
