Zn²⁺-doped perovskite nanocrystals (NCs) are accepted as photoelectronic materials for used in LED, solar energy and photovoltaic devices but are not yet used in photochemical conversion. To the best of our knowledge, this is the first report of use of Zn²⁺-doped CsPbBr₃ NCs borosilicate glass powder in water for hydrogen production. The research results show that the doped nanocrystals perovskite decomposition hydrogen water effect is better than that of pure perovskite nanocrystals, and its hydrogen generation rate reached 127 μmol/g. In addition, Zn²⁺ -doped CsPbBr₃ perovskite NCs glass also greatly solves the problems of water, light and chemical instability, including rapid deactivation. The photocatalytic hydrogen production rule of with different Zn²⁺ doping amounts and the photocatalytic hydrogen production effect with different nanocrystalline concentrations were also investigated.

Zn ²⁺掺杂的钙钛矿纳米晶体（NCs）被用作用于LED，太阳能和光伏器件的光电材料，但尚未用于光化学转化。据我们所知，这是首次在水中使用Zn ²⁺掺杂的CsPbBr ₃ NCs硼硅酸盐玻璃粉生产氢气的报道。研究结果表明，掺杂的纳米晶钙钛矿分解氢水的效果优于纯钙钛矿纳米晶，其氢生成速率达到127μmol/ g。此外，Zn ²⁺掺杂的CsPbBr ₃钙钛矿NCs玻璃还极大地解决了水，光和化学不稳定性的问题，包括快速失活。研究了不同Zn ²⁺掺杂量的光催化制氢规律以及不同纳米晶浓度的光催化制氢效果。
