Photocatalytic Water Splitting into Hydrogen Production Performance of Schottky-type Zn0.11Co0.42Ni0.47Se/ZnIn2S4 Composites
摘要
Abstract
Schottky-type Zn0.11Co0.42Ni0.47Se/ZnIn2S4(ZCNSe/ZIS)composites were constructed by a two-step hydrothermal/water-bath method.The influence of phase composition,morphological structure,interfacial structure,band alignment and photothermal effect on the hydrogen evolution reaction(HER)was investigated.The photocatalytic mechanism was discussed.The results indicate that ZCNSe/ZIS samples exhibit excellent photothermal effect,which effectively improves the visible-light and near-infrared-light absorption.Simultaneously,the Schottky contact facilitates the carrier separation and suppresses the electron-hole recombination.Consequently,the HER performance is enhanced markedly,and the optimal ZCNSe-4/ZIS sample achieves a hydrogen evolution rate of 6.89 mmol·g-1·h-1,which is ca.3.48 times higher than that of pristine ZIS(1.98 mmol·g-1·h-1).Moreover,band structure,photoelectron dynamics and photothermal characterizations collectively corroborate the photogenerated carrier transfer mechanism in Schottky-type ZCNSe/ZIS composites.关键词
