Abstract N-doped porous carbon (NPC) was produced through a simple and efficient method using biomass-derived pine sawdust as the carbon source, NH 4 Cl as nitrogen source and NaHCO 3 as the activator. Both NPC and porous carbon (PC, prepared without nitrogen-doping) were used as support for Au nanoparticles to catalytic oxidation of benzyl alcohol. As expected, Au/NPC performs a substantially enhanced catalytic activity for benzyl alcohol oxidation in comparison with that of Au/PC (conversion of benzyl alcohol is 98.9% for Au/NPC and 51.4% for Au/PC under the same condition). The better catalytic performance of Au/NPC should be due to the introduction of N atoms into PC support, which not only adsorbs the benzyl alcohol molecules more easily, but also makes the Au nanoparticles smaller and more dispersed. Our experimental results also show that mild temperature (60 °C) is more beneficial for the reaction, O 2 atmosphere is a necessity for benzyl alcohol oxidation and Au/NPC can also be used to catalyze oxidation of other aromatic alcohols.

用于苯甲醇氧化的 N 掺杂多孔碳负载 Au 纳米颗粒

摘要 以生物质松木屑为碳源，NH 4 Cl 为氮源，NaHCO 3 为活化剂，通过一种简便高效的方法制备了掺氮多孔碳（NPC）。NPC 和多孔碳（PC，未掺杂氮制备）均用作 Au 纳米颗粒的载体，以催化氧化苯甲醇。正如预期的那样，与 Au/PC 相比，Au/NPC 对苯甲醇氧化的催化活性显着提高（在相同条件下，Au/NPC 苯甲醇的转化率为 98.9%，Au/PC 为 51.4%）。Au/NPC更好的催化性能应该是由于在PC载体中引入了N原子，不仅更容易吸附苯甲醇分子，而且使Au纳米颗粒更小、更分散。我们的实验结果还表明，温和的温度（60 °C）更有利于反应，O 2 气氛是苯甲醇氧化的必要条件，Au/NPC 也可用于催化其他芳香醇的氧化。图形摘要
