摘要

以水热法合成了Ni掺杂的纳米Cd

0.1

0.9

S固溶体光催化剂

采用分光光度计、X射线衍射仪和比表面及孔径分析仪对光催化剂结构进行表征

考察了Ni掺杂量(质量分数)对固溶体晶型结构及光催化性能的影响

发现Ni掺杂可以使催化剂吸收边红移、晶体粒径减小、比表面积增大.可见光产氢实验研究表明

最佳的Ni掺杂量为0.1%

此时光催化剂产氢活性达到最大.对该光催化剂负载Pt可以进一步提高其活性

当w(Pt)为0.6%时

产氢速率能够达到117 μmol/h.

Abstract

Ni doped nanocrystalline Cd

S solid solution photocatalysts were prepared by hydrothermal method. All the prepared photocatalysts were characterized by XRD

UV-Vis and BET. The effect of doped Ni on the solid solution crystal structure and photocatalytic performance was examined. It is found that the absorption edge of photocatalysts shifts to longer wavelength with increasing Ni

doping

and doped Ni enables to reduce the particle size and widen the surface area of the photocatalysts. In H

evolution from water under visible light

an optimal Ni doping amount 0.1% makes the photocatalyst possess the best hydrogen production activity

the activity is able to be improved under the optimum loading P

t of 0.6%

which is explained in detail. The hydrogen production rate reaches to 117 μmol/h.
