Halloysite nanotube-supported bismuth catalysts for acetylene hydrochlorination

A novel supported bismuth (Bi)-based catalyst was prepared using halloysite nanotubes (HNTs) as a carrier and effectively used for acetylene hydrochlorination. The proposed Bi/HNT catalyst exhibited potential catalytic performance. The loss of active species (Bi species) and the accumulation of carbon deposition on the surface are the main reasons for the Bi/HNT catalyst's deactivation.
