Oxidation of water is a challenging process with a positive free energy change and it is purposeful to find good catalysts to facilitate the process. While the perovskite oxides, LaCoO3 and LaMnO3, are good electron transfer catalysts in artificial photosynthesis to produce oxygen by the oxidation of water, the electron transfer is further favoured by the presence of platinum nanoparticles, causing a substantial increase in oxygen evolution.
水的氧化是一个具有正自由能变化的挑战性过程,寻找良好的催化剂来促进这一过程是很有意义的。虽然钙钛矿氧化物LaCoO₃和LaMnO₃在人工光合作用中通过水的氧化产生氧气方面是良好的电子转移催化剂,但铂纳米颗粒的存在进一步促进了电子转移,导致析氧量大幅增加。
