“…In contrast, H 2 O 2 , TBHP (tert-butyl hydroperoxide) and O 2 are considered as green oxidants due to their environmental friendliness. Various heterogeneous catalysts based on noble metals (Pd, Au, Ru) or transition metals (Fe, Co, Zn, Ce, Cu, et al) have been reported for this reaction with green oxidants [7]. Zhang et al [8] synthesized a series of Pd/CeO 2 catalysts by exposing different crystal facets of the CeO 2 support and successfully activated O 2 for benzyl alcohol selective oxidation by the most abundant oxygen vacancies and optimized metal-support interaction on the CeO 2 (110) surface.…”

The catalytic oxidation of alcohols is an important transformation in the chemical industry. Carbon materials with a large surface area and N doping show great promise as metal-free catalysts for the reaction. In this study, a rich N-containing covalent triazine framework polymerized by cyanuric chloride and p-phenylenediamine was used to synthesize N-doped porous carbon with the assistance of a pore-forming agent—NaCl. First, the mass ratio of the polymer/NaCl was optimized to 1:9. Then, the influence of the pyrolysis temperatures (700–1000 °C) on the materials was studied in detail. It was found that the carbon materials were gradually exfoliated by molten salt at high temperatures. XRD and Raman characterizations showed them with a certain graphitization. The optimal doped carbon CNN-1-9-900 achieved the highest surface area of 199.03 m2g−1 with the largest pore volume of 0.29 cm3g−1. Furthermore, it had a high N content of 9.9 at% with the highest relative proportion of pyridinic/graphitic N. Due to the synergistic effect between the surface area and pyridinic/graphitic N, CNN-1-9-900 showed the best performance for benzyl alcohol oxidation with TBHP at moderate conditions, and the process also worked for its derivatives.
