The addition of yttrium chloride （YC13） to an activated carbon-supported Au catalyst （AuIAC） canmarkedly promote the catalytic performance of acetylene hydrochlorination to the vinyl chloridemonomer （VCM）. The structure and physicochemical features of the YCl3-modified catalysts （Y-Au/AC）were measur...
