Web围绕这一科学问题,2015级博士生居佃兴在陶绪堂教授的指导下,对DMASnI3材料进行研究,发现该材料在空气中其颜色逐渐加深,光学带隙逐渐变窄,但其晶体结构保持不变。他们通过综合利用X射线衍射、Raman光谱,XPS以及DFT计算等手段揭示了其带隙变窄机理。 WebThe density functional theory (DFT) calculations further shed light on the intrinsic water‐stable mechanism of DMASnI3 perovskite, which is ascribed to the higher water surface adsorption energy, the higher water osmotic energy barrier, and the smaller intralayer spacing inside DMASnI3 structures by comparing with Pb‐based counterpart.
WebContrary to other hybrid perovskites, DMASnI3 crystals exhibit excellent water phase stability. For example, DMASnI3 was immersed in DI water for 16 h and no decomposition was observed. Inspired by its excellent water phase stability, we demonstrate a potential eco-friendly application of DMASnI3 in photo-catalysis for H2 evolution in DI water.
