Pyrolysis of dichloroethane is an important reaction for the production of vinyl chloride monomer. The high operating temperature and low efficiency are, however, nuisances for this process. In this manuscript, a supported structure-controlled graphitic carbon nitride is reported as a highly efficient catalyst for dehydrochlorination of 1,2-dichloroethane (1,2-DCE). The results indicate that the “defects” of the active component, i.e., the chain terminations of the carbon nitride, which tend to form at low synthesis temperature of the catalyst, show high catalytic activities for the dehydrochlorination of 1,2-dichloroethane, while for the high degree of polymerization of carbon nitride, which tends to increase at high synthesis temperature, relatively low activities for the reaction can be found. These findings highlight the role of the “defects”, i.e., chain terminations, of the material in the reaction and also provide a strategy for the selective synthesis of highly active N-doped carbon catalysts for this reaction.

负载型结构控制的石墨氮化碳催化剂用于1,2-二氯乙烷的脱氯化氢†

二氯乙烷的热解是生产氯乙烯单体的重要反应。然而，高工作温度和低效率是该过程的麻烦。在该手稿中，据报道，担载结构控制的石墨氮化碳是一种高效的1,2-二氯乙烷（1,2-DCE）脱氯化氢催化剂。结果表明活性成分的“缺陷”，即，倾向于在催化剂的低合成温度下形成的氮化碳的链末端显示出对1,2-二氯乙烷脱氯化氢的高催化活性，而对于氮化碳的高聚合度则倾向于增加在高合成温度下，可以发现该反应的活性相对较低。这些发现突出了材料在反应中的“缺陷”即链终止的作用，并且还提供了用于该反应的高活性氮掺杂碳催化剂的选择性合成的策略。
