Promotional effect of copper(ii) on an activated carbon supported low content bimetallic gold–cesium(i) catalyst in acetylene hydrochlorination

Cu-added low content AuCs/AC worked as highly active, stable and cost-effective catalyst for acetylene hydrochlorination. Our findings suggest that the AuCuCs/AC catalyst can be envisioned as a viable alternative to commercial toxic HgCl₂for acetylene hydrochlorination.
