Recent trends in the area of catalytic applications of metal–organic framework (MOF)-derived nanocarbons are covered. These highly porous nanostructures, convenient for the green chemistry processes, are generally formed by the direct carbonization of a variety of MOF, mainly MOF-5, ZIF-8, ZIF-67, UiO-66-NH2, MIL-101-NH2 at 700–1000 °C in argon or nitrogen flow. Differences between conventional porous carbons and MOF-derived carbons are in pore volumes, surface area, and presence of ad-atoms. The morphology of the MOF-derived nanocarbons can be adjustable with uniform dopant distribution. Resulting nanocarbons are widely applied in heterogeneous catalysis, photocatalysis and are very promising as electrocatalysts, having excellent performance in oxygen evolution reaction, oxygen reduction reaction, and hydrogen evolution reaction. Catalytic applications for environmental purposes are also discussed. Good catalytic performance is related with highly dispersed heteroatoms, density of catalytic active sites, controllable porosity, and high surface area. Opportunities for further research are indicated, in particular, the creation of low pH-stable electrocatalysts and novel strategies for the preparation of 1÷3D single-atom catalysts.

使用金属-有机骨架衍生的纳米碳催化:近期趋势

涵盖了金属-有机骨架(MOF)衍生的纳米碳催化应用领域的最新趋势。这些高度多孔的纳米结构便于绿色化学过程,通常是由多种MOF(主要是MOF-5,ZIF-8,ZIF-67,UiO-66-NH 2,MIL-101-NH)直接碳化形成的2在700-1000°C的氩气或氮气流中。常规多孔碳和MOF衍生的碳之间的差异在于孔体积,表面积和Ad原子的存在。MOF衍生的纳米碳的形态可以通过均匀的掺杂剂分布进行调整。所得的纳米碳被广泛地用于多相催化,光催化中,并且作为电催化剂非常有前途,在氧析出反应,氧还原反应和氢析出反应中具有优异的性能。还讨论了出于环境目的的催化应用。良好的催化性能与高度分散的杂原子,催化活性位点的密度,可控制的孔隙率和高表面积有关。指出了进一步研究的机会,特别是,
