摘要

开发稳定的光催化膜对与太阳能-氢能转化以及污染物降解具有重要的现实意义, 然而至今仍是一个大挑战。本工作采用热蒸与化学气相沉积 (CVD) 法在FTO上连续沉积MoS2和PtSe2制备一种稳定的MoS2/PtSe2/FTO光催化薄膜。优化的MoS2/PtSe2/FTO膜的光催化产氢速率1560 mmol·h−1·m−2, 远远高于FTO和其它单MX2/FTO。而且, MoS2/PtSe2/FTO膜具有良好的材料结构和性能稳定性, 在100 h的持续光催化实验中光催化性能没有减弱。一系列电/光谱检测证实了2D/2D异质结构的MoS2/PtSe2有利于FTO上光生电子-空穴的分离和转移, 有效抑制了电荷复合。MoS2/PtSe2/FTO膜显示出巨大的潜力作为一个稳定高效的光催化剂应用在太阳能-氢能和污染物降解领域。
