“…The C2H2-TPD, FT-IR, HCl adsorption/desorption experiments and Rideal-Eley mechanism [48,49] was used to investigate the reaction mechanism of (C6H5)Cl3Sn/AC in acetylene hydrochlorination. In addition, (C6H5)Cl3Sn/AC was separately pretreated with HCl, C2H2 and N2 at 180 °C for 1 h. Later on, (C6H5)Cl3Sn/AC-HCl, (C6H5)Cl3Sn/AC-C2H2, (C6H5)Cl3Sn/AC-N2 was characterized by FT-IR techniques, respectively.…”

The catalysts that comprising the main active compounds of Sn-Nx were synthesized using trichlorophenylstannane ((C6H5)Cl3Sn), nitrogen carbon-dots (NCDs), and activated carbon (AC) as starting materials, and the activity and stability of catalysts was evaluated in the acetylene hydrochlorination. According to the results on the physical and chemical properties of catalysts (TEM, XRD, BET, XPS and TG), it is concluded that NCDs@AC can increase (C6H5)Cl3Sn dispersity, retard the coke deposition of (C6H5)Cl3Sn/AC and lessen the loss of (C6H5)Cl3Sn, thereby further promoting the stability of (C6H5)Cl3Sn/AC. Basing from the characterization results of C2H2-TPD and HCl adsorption experiments, we proposed that the existence of Sn-Nx can effectively strengthen the reactants adsorption of catalysts. By combing the FT-IR, C2H2-TPD and Rideal-Eley mechanism, the catalytic mechanism that C2H2 is firstly adsorbed on (C6H5)Cl3Sn to form (C6H5)Cl3Sn-C2H2 and then reacted with HCl to produce vinyl chloride, is proposed.
