After the Gold Rush: Stop–start scanning transmission electron microscopy was used to track gold (Au) species formed during the low-temperature water–gas shift reaction over Au/CeZrO4. Au nanoparticles formed during the heating of the catalyst to reaction temperature agglomerate under reaction conditions. X-ray photoelectron spectroscopy reveals that catalyst deactivation is an outcome of particle agglomeration.

低温水煤气变换反应中金/二氧化锆-锆的活化和失活

在淘金热之后:停止-开始扫描透射电子显微镜用于追踪在Au / CeZrO 4上的低温水煤气变换反应过程中形成的金(Au)物种。在反应条件下,将催化剂加热至反应温度期间形成的Au纳米颗粒附聚。X射线光电子能谱显示催化剂失活是颗粒团聚的结果。
