The impressive optoelectronic performance and low production cost of metal halide perovskites have inspired applications well beyond efficient solar cells. Herein, we widen the materials engineering options available for the efficient and selective photocatalytic oxidation of benzylic alcohols, an industrially significant reaction, using formamidinium lead bromide (FAPbBr3) and other perovskite-based materials. The best performance was obtained using a FAPbBr3/TiO2 hybrid photocatalyst under simulated solar illumination. Detailed optical studies reveal the synergetic photophysical pathways arising in FAPbBr3/TiO2 composites. An experimentally supported model rationalizing the large conversion enhancement over the pure constituents shows that this strategy offers new prospects for metal halide perovskites in photocatalytic applications.

有机-无机钙钛矿杂化材料对苯甲醇的高效选择性光催化氧化

令人印象深刻的光电性能和较低的金属卤化物钙钛矿生产成本,已经激发了除高效太阳能电池以外的应用领域。在此,我们拓宽了使用甲酰胺基溴化铅(FAPbBr 3)和其他钙钛矿基材料进行苄基醇的高效和选择性光催化氧化的工业实用的材料工程选择范围。使用FAPbBr 3 / TiO 2杂化光催化剂在模拟太阳光照下可获得最佳性能。详细的光学研究揭示了FAPbBr 3 / TiO 2中产生的协同光物理途径复合材料。一个实验性支持的模型,该模型合理化了对纯组分的大幅提高转化率,表明该策略为光催化应用中的金属卤化物钙钛矿提供了新的前景。
