摘要：Developing efficient, sustainable, and stable nanocatalysts continue being the struggling goal both for academia and for industrial. Carbocatalysts have attracted great attention due to high mass transfer ability, environmental sustainability and stability. Fabricating well-defined carbonaceous nanocatalysts for heterogeneous catalysis is intensively pursuing. In this work, a newly developed economic and facile method was applied for the large-scale fabrication of graphite sheet encapsulated magnetic carbocatalysts. The carbocatalysts was constructed via in-situ pyrolysis of melamine-metallo-supramolecular polymer precursors (MMSP) under vacuum condition. The framework of MMSP was synthesized through the condensation reaction. As a proof-of-concept, this method was successfully applied for the fabrication of three kinds of graphite encapsulated magnetic carbocatalysts. Based on systematically optimization, the Pt-NiO-1000@NC-650 nanocatalyst demonstrated highly efficient and remarkable stability for the catalytic transfer hydrogenation of 4-nitrophenol to produce corresponding 4-aminophenol. The kinetics study of this catalytic system illustrates the reaction order is 1st for Pt-NiO-1000@NC-650. Furthermore, the kinetic constant (K-app) is 1.57 min(-1) and the turnover frequency (TOF) is up to 4, 268 h(-1).
