A polyaniline (PANI)-modified zeolite Y supported Pd catalyst (Pd/PANI-HY) for acetylene hydrochlorination was successfully synthesized by ultrasonic-assisted impregnation. The catalyst exhibited excellent stability, and acetylene conversion was maintained at >95% more than 300 h. The excellent stability of the Pd/PANI-HY catalyst was attributed to the presence of the polyaniline that partly weakens the occurrence of carbon deposition and also inhibited the reduction of the Pd2+ active component on the catalyst surface.
