An Au–Cu bimetal catalyst for acetylene hydrochlorination with renewable γ-Al2O3 as the support

The bimetal catalyst gold(iii) chloride–copper(ii) chloride (AuCl₃–CuCl₂) was prepared with different gamma-aluminium oxide (γ-Al₂O₃) supports and its catalytic properties towards acetylene hydrochlorination were assessed in a fixed-bed reactor.
