In this study, a sulphur and nitrogen dual-doped carbon catalyst was prepared via an easy route with p-phenyldiamine and (NH₄)₂S₂O₈ as the nitrogen and sulphur source, respectively. The obtained catalyst displayed efficient acetylene conversion for acetylene hydrochlorination, and the presence of sulphur enhanced the catalytic activity of the nitrogen-doped carbon catalyst. These catalysts show that sulphur and nitrogen have a synergistic effect for acetylene hydrochlorination. Furthermore, because of the addition of different sulphur contents, the pyrrolic N content causes certain changes in the catalysts, resulting in differences in the catalytic activity. Theoretical investigations reveal that the adsorption ability of C₂H₂ was enhanced by the doping of the S and N-doped carbon catalyst. This is an environmentally friendly catalyst with a broad development prospect and is cheap and easy to obtain.

在这项研究中，通过对苯二胺和（NH ₄）₂ S ₂ O ₈的简便方法制备了硫和氮双掺杂碳催化剂。分别作为氮和硫的来源 所获得的催化剂显示出用于乙炔氢氯化的有效乙炔转化，并且硫的存在增强了氮掺杂碳催化剂的催化活性。这些催化剂表明，硫和氮对于乙炔氢氯化具有协同作用。此外，由于添加了不同的硫含量，吡咯N含量引起催化剂的某些变化，从而导致催化活性的差异。理论研究表明，掺杂S和N掺杂的碳催化剂可提高C ₂ H ₂的吸附能力。这是一种环境友好的催化剂，具有广阔的发展前景，并且价格便宜且易于获得。
