AuCl3 on polypyrrole-modified carbon nanotubes as acetylene hydrochlorination catalysts

- AuCl3/PPy-MWCNT catalyst was prepared and used for acetylene hydrochlorination.
- AuCl3/PPy-MWCNT displayed enhanced catalytic performance than AuCl3/MWCNT.
- Presence of PPy species increased the adsorption of HCl reactant in acetylene hydrochlorination.
