摘　　要：Nitrogen-rich zeolitic imidazolate frameworks(ZIFs)are ideal precursors for the synthesis of metal single atoms anchored on N-doped carbon.However,the microporous structures of conventional ZIFs lead to low mass transfer efficiency and low metal utilization of their derivatives.Here,we construct a composite of Co single atoms anchored on nitrogen-doped carbon with a three-dimensional ordered macroporous structure(Co-SA/3DOM-NC)by two-step pyrolysis of ordered macro/microporous ZnCo-ZIF.Co-SA/3DOM-NC shows high activity in the oxidative esterification of furfural,achieving a 99%yield of methyl 2-furoate under mild reaction conditions,which is significantly superior to the microporous and the Conanoparticle counterparts.The high activity of Co-SA/3DOM-NC should be attributed to the CoN4 centers with high intrinsic activity and the ordered macroporous structure,promoting the mass transfer of reactants and accessibility of active sites.
