Abstract

Two types of poly-porphyrin-based heterogeneous photocatalysts including insoluble polymer and water-soluble nanoparticles exhibited excellent photocatalytic activity in visible-light-induced dehydrogenation in water. The extremely low catalyst loading (0.01 ​mol%) of water-soluble nanoparticles provided so far the highest turnover frequency (TOF) value (333 h-1) for such transformation among reported records.

用于水介质中绿色光催化脱氢的无金属和水兼容纳米催化剂
两种聚卟啉基异相光催化剂(包括不溶性聚合物和水溶性纳米粒子)在可见光诱导的水中脱氢反应中表现出优异的光催化活性。水溶性纳米粒子的催化剂负载量极低(0.01 摩尔%),其转化频率(TOF)值(333 h-1)是迄今所报道的此类转化中最高的。
