Supported catalyst with metal/nitrogen carbon-metal phosphate interface and preparation method and application thereof

The invention discloses a supported catalyst with a metal/nitrogen carbon-metal phosphate interface. The general formula of the supported catalyst is M1/NC-M2 (PO4) x or M1/NC-HAP, wherein the active metal M1 is selected from one or more of non-noble metals Ni, Cu, Fe and Co; nC represents a nitrogen-carbon layer for carrier modification; m2 represents a metal in the support metal phosphate and is selected from one or more of Mn, A1, Pb, Ca, Mg, Zr, Ce and La; the value of x is in the range of 0.1 to 3; and HAP represents hydroxyapatite. The catalyst is prepared by modifying carrier metal phosphate or HAP through a nitrogen-carbon layer, then carrying out heat treatment to obtain a modified carrier, loading active metal through an impregnation method, drying and then reducing in a hydrogen atmosphere. The catalyst provided by the invention can realize various catalytic hydrogenation reduction reactions under mild conditions. 本发明公开了一种通式为M1/NC-M2(PO4)x或M1/NC-HAP的具有金属/氮碳-金属磷酸盐界面的负载型催化剂，其中活性金属M1选自非贵金属Ni、Cu、Fe和Co中
