Au-Cs/AC Modified with Nitrogen As Catalyst in the Hydrochlorination of Acetylene

We demonstrated that the doping of nitrogen can efficiently enhance the catalytic performance of Au-Cs(I) catalysts for acetylene hydrochlorination. The nitrogen atoms strongly interacted with Au species and strengthened the ability of the resultant catalysts to adsorb hydrogen chloride and inhibit the reduction of Au³⁺ to Au⁰ during acetylene hydrochlorination.
