负载型贵金属催化剂是一类组成、结构高度复杂的功能材料,它们的催化性能往往与其中金属的组成、尺寸和形貌、载体的性质以及助剂等参数密切相关,对催化剂的性能优化有赖于深入理解这些参数如何影响催化性能,并对其中的决定参数进行有效调控.在过去的40年里,以理想单晶表面为模型催化剂,借助各种高真空表征技术,表面科学对催化学科的发展起到了很大的推动作用.然而,表面科学与
Supported noble metal catalysts are a kind of functional materials with complex composition and highly complex structure. Their catalytic properties are closely related to the composition, size and morphology of the metal, the nature of the carrier, and the additives and other parameters. The optimization of the catalyst performance depends on In-depth understanding of how these parameters affect the catalytic performance, and the effective control of which decision parameters in the past 40 years, the ideal single-crystal surface model catalyst, with a variety of high-vacuum characterization techniques, surface science on the development of the catalytic discipline Played a great role in promoting.However, surface science and
