Abstract: A plant leaves-derived carbon material doped with two metals and preparation and use thereof are provided, the carbon material prepared by carbonizing, in an inert atmosphere, plant leaves which have absorbed ions of two metals M1 and M2. The metal M1 is Co, Mn, or Fe. The metal M2 is Ni, Cu, or Zn. The carbon material can be used as an efficient, green, and safe catalyst for the selective oxidation of cycloalkanes to produce cycloalkanols and cycloalkanones, and enable an increased selectivity of the target products (thus less by-products), a low yield of cycloalkyl peroxides, reduced reaction temperature, low environmental impact, and safe production.
