| 摘 要： | 多相光催化"全"分解水制H_2的研究已走过约40年路程,至今未获得真正的突破,目前国内、外发表的许多可见光催化牺牲体系放H_2的文章,虽然它在氢离子还原机理方面有一定的参考意义,但它不能解决光催化"全"分解水制H_2问题,本文提醒我国光催化界:勿把可见光牺牲体系产H_2研究的结果,当成我们在分解水制H,方面取得的进展,应认真总结过去失败的经验教训,兼顾热力学和动力学两方面的要求,制订出正确的"全"分解水制H_2催化剂的研究策略。

| Abstract: | Although the study on the over-all photosplitting of water into H_2 and O_2 can be traced backed to ca.40 years ago,a real breakthrough has not been achieved in this field so far.Currently available published studies of H_2 evolution based on sacrificial systems by visible light at home and abroad may be meaningful in helping understand the reduction mechanism of hydrogen ion,but they are inapplicable to solving the problems emerging in over-all photosplitting of water.Thus the domestic academic circles inv... |
