中文摘要
翻译
氧化物负载的金属催化剂是非均相工艺的关键材料,从排放修复到碳氢化合物氧化再到燃料电池技术。这些催化剂通常包含纳米到微米大小的分散金属颗粒,分散在氧化物(如二氧化硅、氧化铝或氧化锆)的基体中。尽管氧化物负载的金属催化剂得到了广泛的应用,但仍有许多问题没有得到解答:载体的作用是什么?,哪些是活性位点?反应机制是什么?中间产物是什么?它们是如何干扰反应的?即使在燃料电池电催化剂中使用的极高负载情况下,有关活性位点、机制和中间体的问题仍不清楚。
英文摘要
Oxide supported metal catalysts are key materials in heterogeneous processes ranging from emissions remediation to hydrocarbon oxidation to fuel cell technology. These catalysts generally involve disperse metal particles of nano to micrometer size dispersed in the matrix of an oxide such as silica, alumina or zirconia. Despite their widespread use, many questions remain unanswered for oxide supported metal catalysts: what is the role of the support?, what are the active sites?, what are the reaction mechanisms?, what are the intermediates and how do they interfere with the reaction? Even in the extremely high loading cases used in the electro-catalysts of fuel cells, issues regarding active sites, mechanism, and intermediates remain unclear.
