摘要
碳材料作为一种廉价易得的非金属催化剂,可以替代传统的金属催化剂应用于傅克反应、氧化反应、碳-氢活化等相关反应中。大比表面积和杂原子可控掺杂是提高碳催化剂催化活性的关键。在最近的研究中,我们利用聚(六氯三聚磷腈-双酚硫)同时含有氮/磷/硫杂原子特点,在金属有机框架化合物ZIF-67和C3N4纳米片表面包覆一层上述聚合物,经高温碳化成功构筑了氮/磷/硫高度均匀共掺杂的中空碳壳和"类石墨烯"非金属催化剂。制得掺杂碳材料具有比表面积大、氮/磷/硫高度均匀共掺杂和表面超亲水性等特点,实现了水体系下芳香烷烃的高效选择性催化氧化。
Carbon materials can be used as low-cost metal-free catalysts for Friedel-Crafts alkylation reactions,oxidation reactions and C-H activation reactions.The two most important factors for their high activity are surface area and doping.In our recent researches,making use of poly(cyclotriphosphazene-co-4,4'-sulfonyldiphenol)(PZS),we prepared ZIF-67@PZS and C_3N_4 nanosheet @PZS composites,which were then calcined to obtain NPS co-doped hollow carbon shells and carbon nanosheets.The prepared doped carbon materials can be used as superior metal-free carbocatalysts for selective oxidation of aromatic alkanes in aqueous solution.
