一种暴露CeO2{100}晶面的铈钛复合氧化物合成及其负载Au催化剂一氧化碳低温氧化性能研究
Controllable synthesis of a 3D flower-like CeTiOx composite oxide exposing CeO2{100} plane and it supported Au catalyst for CO oxidation
摘要
Abstract
In this work, a flower-like CeTiOx composite oxide, predominantly exposing CeO2{100} plane, was synthesized by a simple hydrothermal method.The SEM and XRD results revealed the growth mechanism of CeTiOx composite oxide can be divided into two stages, including the rapid growth of amorphous and the following crystallization.The ratio of Ce/Ti, KOH concentration, crystallization time and calcination temperature are the key factors for the synthesis of the flower-like CeTiOx composite oxide.Au catalyst supported on this composite oxide exhibited superior activity for CO oxidation at room temperature.The TEM and H2-TPR results suggested that the exposed CeO2{100} plane and the strong interaction between Au and CeTiOx composite oxide are responsible for the high activity.关键词
