This is a study of the "ligand effect" in bimetallic catalysts. This is the influence of the local (atomic) environment on the behavior of a catalytic atom. It is difficult to study because of other effects which might occur to mask it and because determination of atomic environments in alloys stretches the limits of surface analysis. As part of this work, a new technqiue for determining such environments will be developed using small-angle x-ray scattering from a synchrotron source.

这是对双金属催化剂中的“配位效应”的研究。这就是局域(原子)环境对催化原子行为的影响。这很难研究，因为可能会发生其他影响，以掩盖它，因为确定合金中的原子环境扩大了表面分析的限制。作为这项工作的一部分，将开发一种利用同步加速器源的小角x射线散射来确定这种环境的新技术。
