| 英文摘要 | acetylene hydrochlorination is an important coal-based technology for the industrial production of vinyl chloride, however it is plagued by the toxicity of the mercury chloride catalyst. therefore extensive efforts have been made to explore alternative catalysts with various metals. here we report that a nanocomposite of nitrogen- doped carbon derived from silicon carbide activates acetylene directly for hydrochlorination in the absence of additional metal species. the catalyst delivers stable performance during a 150 hour test with acetylene conversion reaching 80% and vinyl chloride selectivity over 98% at 200 degrees c. experimental studies and theoretical simulations reveal that the carbon atoms bonded with pyrrolic nitrogen atoms are the active sites. this proof- of- concept study demonstrates that such a nanocomposite is a potential substitute for mercury while further work is still necessary to bring this to the industrial stage. furthermore, the finding also provides guidance for design of carbon- based catalysts for activation of other alkynes. |
