摘　　要：综述了近年来非碳载体材料(碳化物、氧化物、复合型氧化物、亚化学计量钛氧化物等)的研究动态,介绍了其特点和制备方法,重点评价了以其为载体的铂基催化剂的催化活性及稳定性,并与目前普遍采用的商业碳载铂(Pt/C)催化剂进行了比较.最后,对非碳材料用作载体存在的问题进行了分析,并对此类载体材料的发展方向进行了展望,提出高比表面、高电导率、高稳定性非碳载体材料的合成及载体与贵金属之间强相互作用机理的研究是载体研究的主要方向.The recent research progress in non-carbon materials supports, such as carbide, oxide, composite oxide and sub-stoichiometric titanium oxide, is reviewed. Their characteristics and preparation methods are described briefly. The emphasis focuses on the catalytic activity and stability of Pt based catalysts supported on the materials. Comparison has been drawn between non-carbon supported and commercial carbon supported catalyst （Pt/C）. Finally, the defects of non-carbon materials are summarized and outlook for the future development of this kind of support materials and further investigation of mechanism are provided in light of the current research status, regarding the preparation of materials with high specific surface area, high conductivity and superior stability, as well as mechanism of strong metal support interaction.
