superior catalytic performance in the aerobic dehydrogenation of various heterocyclic nitrogen compounds (49 examples, up to 96% yield), similar to that of C3N4 and GO. Characterization by TEM, BET and XPS accompanied by the EPR analysis revealed that the enhanced catalytic properties of NC came from its high activation ability for both O2 and heterocyclic nitrogen, attributed to the porous structure and
N 掺杂的多孔碳 (NC) 是由甘蔗渣合成的,甘蔗渣是一种可持续且广泛使用的生物质废物。优选的 NC 样品具有发达的多孔结构、类似石墨烯的表面形态和不同的 N 种类。更重要的是,多相碳催化剂在各种杂环氮化合物的有氧脱氢反应中表现出优异的催化性能(49个例子,产率高达96%),类似于C 3 N 4和GO。TEM、BET 和 XPS 表征以及 EPR 分析表明,NC 的增强催化性能来自其对 O 2和杂环氮的高活化能力,分别归因于多孔结构和吡啶 N (N-6) 物种.
