摘要： 利用气-固相反应初步考察了几种常用半导体光催化剂在无氧条件下分解硫化氢产氢的活性. 在研究的TiO2, CdS, ZnS, ZnO和ZnIn2S4等催化剂中, ZnS具有较高的光催化产氢活性. 在ZnS上担载贵金属Ir可明显提高产氢速率,在ZnS制备过程中加入少量Cu2+可极大地提高H2S的分解速率.

Abstract: Hydrogen production by gas-solid phase photocatalytic splitting of H2S was investigated on five semiconductor photocatalysts including TiO2, CdS, ZnS, ZnO, and ZnIn2S4. ZnS shows the highest rate of hydrogen production under the identical conditions. Loading Ir on ZnS can effectively promote the hydrogen production. The addition of Cu2+during the ZnS preparation significantly enhances the photocatalytic activity of the catalyst for hydrogen production.
