Particle Size Effects and Metal Support Interactions in Electrocatalysis

在这个由分析和表面化学项目支持的合作研究项目中，Scherson教授和Chottiner教授提出了一项系统的研究，研究铂粒度对不同碳基质上铂的电催化性能的影响。一系列不同形态的碳衬底将被检查，并将使用一系列现代表面分析方法来表征支撑金属系统的结构和性能。这项工作将为理解电催化过程提供重要的信息，并利用共同主要研究人员在电化学，表面分析和材料研究方面的互补专业知识。使用一系列表面分析方法，将对不同碳基质上铂催化剂的铂粒度效应进行研究。从这些研究中获得的理解将对燃料电池电极和其他电催化装置的设计非常有用。

In this collaborative research project, supported by the Analytical and Surface Chemistry Program, Professors Scherson and Chottiner propose a systematic study of the effects of platinum particle size on the electrocatalytic properties of platinum supported on various carbon substrates. A series of carbon substrates of varying morphology will be examined, and a battery of modern surface analytical methods will be used to characterize the structure and properties of the supported metal system. This work should provide information important to the understanding of electrocatalytic processes, and draws on the complementary expertise in electrochemistry, surface analysis, and materials research of the co-principal investigators. %%% Studies of platinum particle size effects for platinum catalysts supported on various carbon substrates will be carried out using a range of surface analytical methods. The understanding to be gained from these studies will be very useful in the design of fuel cell electrodes and other electrocatalytic devices.
