It is the intent of this proposal to use a new technique, discovered and developed in the applicant's laboratory, symmetric peak component XPS analysis, to determine the interactions between the two metals in a bimetallic alloy nanoparticle. Such alloy nanoparticles often function better as catalysts, sensors, etc., than single-metal nanoparticles but the interactions leading to this improvement are not understood. We intend to study platinium-ruthenium and platinium-molybdenum alloys, which have been found to function better than pure platinium, in direct methanol fuel cells, a candidate replacement for petroleum.

该提议的目的是使用在申请人的实验室中发现和开发的新技术，对称峰分量XPS分析，来确定在镍基合金纳米颗粒中两种金属之间的相互作用。这种合金纳米颗粒通常更好地用作催化剂、传感器等，但是导致这种改进的相互作用尚不清楚。我们打算研究铂-钌和铂-钼合金，这已被发现比纯铂，在直接甲醇燃料电池，石油的候选替代品的功能更好。
