The Preparation of Cu-g-C 3 N 4 /AC Catalyst for Acetylene Hydrochlorination

摘要

A novel catalyst based on g-C 3 N 4 /activated carbon was prepared by adding CuCl 2 . The catalytic performance of the as-prepared catalyst was investigated in the acetylene hydrochlorination reaction. X-ray photoelectron spectroscopy, temperature programmed desorption, low temperature N 2 adsorption/desorption (Brunauer–Emmett–Teller), and thermal gravity analysis showed that Cu-g-C 3 N 4 /AC significantly enhanced the catalytic performance of the original catalyst by increasing the relative pyrrolic N content. Cu-g-C 3 N 4 /AC also affected the adsorption of hydrogen chloride and acetylene, as well as inhibited the coke deposition during acetylene hydrochlorination.
