镁基储氢材料催化的研究进展

Research Progress of Catalysts for Mg-based Hydrogen Storage Materials

过去十几年国内外对镁基储氢材料的催化剂研究表明,使用催化剂能够有效改善材料的表面特性,提高材料的吸放氢动力学性能。目前常用的催化剂体系有过渡族金属、金属氧化物、金属卤化物、金属间化合物以及碳素非金属。通过比较发现,不同种类的催化剂催化效果不同,相应的催化机理也有所差异。目前,国外研究者已发现几种催化剂共同催化的效果显著,国内应加强金属间化合物和碳素材料催化剂以及不同催化剂共同作用方面的研究。

The catalysts of Mg-based hydrogen storage materials are studied in the past decades. It shows that catalysis is one of the critical factors in improving hydrogen sorption kinetics for metal hydride systems. All the catalysts are consisting of transition metals, metal oxides, metal halides, intermetallic compounds and non-metal compounds. The intermetallic compounds and non-metal compounds show great catalysis abilities in recent researchs. The catalytic effect and catalytic mechanism of all above catalysts are reviewed.
