摘要
综述了制备Magnéli相Ti4O7的H2还原TiO2、C还原TiO2和机械活化Ti和TiO2及两步法合成等4种方法的研究现状及其优缺点,以及研究Magnéli相Ti4O7在燃料电池中的应用现状。展望了软化学法合成高比表面积的Ti4O7材料作为燃料电池催化剂载体材料的发展趋势。
Magneli phase Ti4O7 material prepared by four methods, reduced TiO2 by H2, reduced TiO2 by C and mechanical activation of TiO2 with Ti, and synthesis through two steps are reviewed, and their advantages and disadvantages are also pointed out. The studies using the Ti4 Or material as a catalyst support in the field of fuel cell are also summed. Soft-chemical synthesis of Ti4O7 material with high specific surface area is proposed as one of the main research directions for catalyst support in the future.
