Surface pits stabilized Au catalyst for low-temperature CO oxidation
文献摘要：
Development of active and stable catalysts for low-temperature CO oxidation has long been regarded as a hot topic.In this contribution,we used CeO2 with high-density surface pits as support to prepare an active and stable Au/CeO2 catalyst by an adsorption-deposition method.The obtained 0.05 wt％Au/CeO2-TD(where TD represents thermal decomposition)can maintain its activity at 80℃for more than 20 h or even after calcination at 800℃ for 2 h.The characterization results showed that the high-density surface pits on CeO2-TD play a decisive role in the stabilization of Au and enhancement of the redox property.This work may provide a new strategy to improve the stability of supported metal catalysts by a simple and conventional method.
