Deposition-Precipitation and Stabilization of a Silica-Supported Au Catalyst by Surface Modification with Carbon Nitride

摘要

A silica support is modified by carbon nitride in order to allow for the deposition-precipitation of Au, which is normally unfavorable. The resulting catalyst is highly stable even after the removal of the carbon nitride layer at high temperature and shows good catalytic activity for the oxidation of CO in air.
