A series of porous carbon (NC) materials were prepared by using in situ-formed aluminophosphate framework as template, and citric acid and sucrose as carbon precursors. The structure and surface chemistry properties of these carbon materials were studied by N(2) adsorption, XRD, DRIFT, and XPS measurements. The catalytic properties of these NC materials were investigated in the selective oxidation of benzyl alcohol with air as oxidant source. Compared with other carbon materials, such as active carbon, mesoporous CMK-3, and carbon molecular sieves, NC materials exhibited much higher catalytic activity with nearly 100% selectivity to benzaldehyde. The presence of abundant surface quinone groups, which originates from the special preparation process of NC material, is likely responsible for the high catalytic property of these porous carbon materials.
一系列多孔碳（NC）材料是通过原位形成的磷酸铝骨架作为模板，柠檬酸和蔗糖作为碳前体制备的。通过 N2 吸附、XRD、DRIFT 和 XPS 测量研究了这些碳材料的结构和表面化学性质。这些 NC 材料在以空气为氧化剂源的苯甲醇选择性氧化反应中表现出很高的催化活性。与其他碳材料如活性炭、介孔 CMK-3 和碳分子筛相比，NC 材料具有更高的催化活性，几乎 100%选择性生成苯甲醛。丰富的表面醌基团的存在，这可能是 NC 材料特殊制备工艺的原因，这也是这些多孔碳材料具有高催化性能的原因。
