Monitoring electrochemical absorption and adsorption processes on noble metal catalysts from XRD

In this experiment, we will investigate the electrochemical absorption and adsorption trends of various chemical species into and onto noble metal nanocatalysts. Both hydrogen absorption on Pd and adsorption on Pt, also with oxide surface formation will be monitored via the lattice strain variation detected from in situ XRD本实验旨在探究多种化学物种在贵金属纳米催化剂内部的电化学吸收及表面的吸附趋势。钯（Pd）表面的氢吸收、铂（Pt）表面的氢吸附以及氧化物表面的形成过程，均将通过原位X射线衍射（in situ XRD）检测到的晶格应变变化进行监测。
