摘要:
传统的Pt碳催化剂,由于仅仅处于纳米粒子表层的Pt原子参与电催化反应,而大多数位于粒子内层的Pt却未能得到有效利用,由此造成的燃料电池高昂成本阻碍了它的大规模商业化进程。核壳结构催化剂是近年来出现的一类极其重要的低铂催化剂,这类催化剂是使用廉价贵金属、过渡金属、合金及导电化合物的纳米粒子作为核,在其表面覆盖原子层厚度或者几个原子层厚度的Pt为壳层而制得的新型高性能催化剂。核壳结构低铂催化剂可大幅度降低燃料电池的贵金属Pt的使用量,进而降低燃料电池的成本,是实现质子交换膜燃料电池大规模商业化的希望所在。有关核壳结构低铂催化剂的研究已成为燃料电池领域最热门的研究课题之一。本文综述了近年来核壳结构低铂催化剂的研究进展,包括核壳结构低铂催化剂制备技术的研究进展,以廉价贵金属、合金及导电化合物纳米粒子作为核的新型核壳结构低铂催化剂的设计、制备及其相关研究情况。介绍了不同类型的核与Pt壳层之间的相互作用,讨论和总结了影响核壳结构低铂催化剂电催化活性的相关因素。并对核壳结构低铂催化剂的研究及其应用进行了展望。关键词:
Abstract:
Traditional Pt/C carbon catalysts, due to the fact that only the Pt atoms in the surface layer of the nanoparticles participate in the electrocatalytic reaction, while most of the Pt in the inner layer of the particles have not been effectively utilized, give rise to the cost of the fuel cell and hinder its commercialization application in large-scale. The low-platinum core-shell catalyst (LPCSC) is a new type of highly active catalyst which employs the nanoparticles of other low price noble metal, transition metal, alloy and conductive compound as the core, where mono layer or several atomic layers of platinum shell deposited on. The LPCSC, which can sharply lower the usage of platinum on fuel cell and thus lower its cost, is considered as the hope for large-scale application of fuel cell. Research about LPCSC has become one of the hottest topics in the field of fuel cell. This review aims to introduce recent advances on LPCSC with highly electrocatalytic activity. We systematically reviewed the latest advances in the preparation methods, and the developments of new type LPCSCs with low price noble metal, alloy and conductive compound as the core, respectively, as well as the investigations on the interaction between the different core and platinum shell. Furthermore, we summarized the affecting factors on the electrocatalytic activity for LPCSC, and prospected the future development and application of the catalysts.
