In this work, we prepared ZnGeP₂ (ZGP) photocatalyst using single flat temperature zone (SFT) method in a vacuum quartz ampoule. The XRD, SEM, EDS, DRS and XPS were used to characterize the crystal structure, morphology, elemental content, optical absorption and band gap structure of ZGP. The results of photocatalytic hydrogen evolution and apparent quantum efficiency show that ZGP is a promising photocatalyst for hydrogen production both under visible and near-infrared light irradiation. In addition, it is also found that adding the common stabilizer H3PO2 and ultrasonic treatment can efficiently improve the photocatalytic activity and stability of ZGP.

ZnGeP 2：一种用于制氢的近红外光催化剂

在这项工作中，我们在真空石英安瓿瓶中使用单一平坦温度区（SFT）方法制备了ZnGeP ₂（ZGP）光催化剂。用XRD，SEM，EDS，DRS和XPS表征了ZGP的晶体结构，形貌，元素含量，光吸收和带隙结构。光催化氢释放和表观量子效率的结果表明，ZGP是可见光和近红外光照射下产生氢的有前途的光催化剂。另外，还发现添加普通的稳定剂H 3 PO 2和超声处理可以有效地改善ZGP的光催化活性和稳定性。
