摘　　要： 介绍了以金属氧化物为介质的热化学循环分解水制氢。与其它循环体系相比,金属氧化物循环仅由两步反应组成,过程简单、不向环境排放有害物质、避免了高温下分离气体的困难。研究发现,以铁酸盐为代表的复合体系有望在较温和的条件下进行反应,如果能与太阳能或者高温核反应堆耦合,则有望成为清洁的、具有经济性的制氢方法。 As an ideal energy cartier duction of hydrogen is the basis of h for the future, hydrogen has been paid much more attention than before. Mass proydrogen energy, while the thermochemical water-splitting is one of the most attactive methods. The thermochemical cycles based on metal oxides were reviewed. These cycles are simple and cabon dioxide emision free, in addition, the difficulty of gases separation at high temperature is avoided. With these advantages, they were considered as a promising way. Furthermore, recent research suggested that the multi-element ferrite system could run under moderate conditions of these cycles coupled with solar reactor or high temperature nuclear reactor, it is prospective to get a clean and economical hydrogen-producing way.
