There is increasing interest in the role of metal halide perovskites for heterogeneous catalysis. Here, we report a Ge-based 2D perovskite material that shows intrinsic water stability realized through organic cation engineering. Incorporating 4-phenylbenzilammonium (PhBz) we demonstrate, by means of extended experimental and computational results, that PhBzGeBr and PhBzGeI can achieve relevant air and water stability. The creation of composites embedding graphitic carbon nitride (g-CN) allows a proof of concept for light-induced hydrogen evolution in an aqueous environment by 2D Ge-based perovskites thanks to the effective charge transfer at the heterojunction between the two semiconductors.
金属卤化物钙钛矿在多相催化中的作用越来越受到关注。在此，我们报道了一种基于锗的二维钙钛矿材料，该材料通过有机阳离子工程实现了内在的水稳定性。通过引入4-苯基苄基铵（PhBz），我们借助大量实验和计算结果证明，PhBzGeBr和PhBzGeI能够实现良好的空气和水稳定性。嵌入石墨相氮化碳（g-CN）的复合材料的制备，为二维锗基钙钛矿在水环境中光致析氢提供了概念验证，这得益于两种半导体之间异质结处的有效电荷转移。
