英文摘要	It is an attractive and challenging topic to endow non-noble metal catalysts with high efficiency via a nitrogen-doping approach. In this study, a nitrogen-doped carbon catalyst with high nitrogen content encapsulating cobalt NPs (CoOx@N-C(g)) was synthesized, and characterized in detail by XRD, HRTEM, N-2-physisorption, ICP, CO2-TPD, and XPS techniques. g-C3N4 nanosheets act as nitrogen source and self-sacrificing templates, giving rise to an ultrahigh nitrogen content of 14.0%, much higher than those using bulk g-C3N4 (4.4%) via the same synthesis procedures. As a result, CoOx@N-C(g) exhibited the highest performance in the oxidative esterification of biomass-derived platform furfural to methylfuroate under base-free conditions, achieving 95.0% conversion and 97.1% selectivity toward methylfuroate under 0.5MPa O-2 at 100 degrees C for 6h, far exceeding those of other cobalt-based catalysts. The high efficiency of CoOx@N-C(g) was closely related to its high ratio of pyridinic nitrogen species that may act as Lewis basic sites as well as its capacity for the activation of dioxygen to superoxide radical O-2(.-).
