Deactivation: This work reveals the catalytic and deactivation mechanisms of Ag/C catalysts during the synthesis process of vinyl chloride using C₂H₂ and HCl gas. AgCl generated by the activation by HCl, as the active site, promotes the reaction. And the reasons of deactivation are the loss of Ag and particle aggregation. This perspective offers a suitable insight for the subsequent research on Ag-based catalysts.

银转化为活性物质（氯化银）对乙炔氢氯化的影响

失活：这项工作揭示了在使用 C ₂ H ₂和 HCl 气体合成氯乙烯过程中 Ag/C 催化剂的催化和失活机制。由作为活性位点的 HCl 活化产生的 AgCl 促进反应。而失活的原因是银的损失和颗粒聚集。这一观点为后续对银基催化剂的研究提供了合适的见解。
