Synthesis, Characterization, and Surface Reactivity of Palladium-Gold Bimetallic Clusters

本文研究了双金属催化剂中的“配体效应”。 这 是局部（原子）环境对 催化原子 由于其他影响， 这可能会掩盖它，因为原子的测定 合金中的环境扩展了表面分析的极限。 作为 这项工作的一部分，一个新的技术来确定这样的环境， 将利用同步加速器的小角度X射线散射 源头

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.
