The N, S-codoped mesoporous carbon catalysts are prepared with a template method by using SBA-15 as the hard template, and phenanthroline and KSCN as the nitrogen and sulfur precursors. The catalyst calcined at 900 °C with relatively high specific surface areas and uniform pore sizes displays the highest catalytic performance among the obtained catalysts for selective oxidation of ethylbenzene, which is attributed to the unique architectures and the synergistic effect of pyridinic-N, graphitic-N, and thiophene-S. The excellent catalytic performance and facile preparation process enable the catalyst to be a promising metal-free substitute for selective oxidation of arylalkanes.

以SBA-15为硬模板，以菲咯啉和KSCN为氮，硫前驱体，采用模板法制备N，S共掺杂的介孔碳催化剂。在900°C下煅烧的具有相对较高的比表面积和均一的孔径的催化剂显示出在获得的乙苯选择性氧化催化剂中具有最高的催化性能，这归因于吡啶-N，石墨-N的独特结构和协同效应。 N和噻吩-S。出色的催化性能和简便的制备方法使该催化剂成为有希望的无金属替代物，可用于芳基烷烃的选择性氧化。
