Abstract: A confined porphyrin Co(II), which is prepared by the following method: Equimolar amounts of aromatic aldehyde and pyrrole are condensed under acidic conditions to synthesize phenyl porphyrin compounds; the phenyl porphyrin compounds are metallized in a chloroform-methanol solution to obtain porphyrin Cu(II), which is brominated and demetallized to obtain confined porphyrin; the confined porphyrin is stirred and refluxed in a methanol solution for 12.0-24.0 h to obtain confined porphyrin Co(II). Its application is as follows: The confined porphyrin Co(II) is dissolved in cycloalkanes; the reaction system is sealed, and heated to 100 to 130° C. with stirring, to which oxygen is introduced to 0.2 to 3.0 MPa; the reaction is carried out for 3.0 to 24.0 h with stirring with the set temperature and oxygen pressure being maintained; and then the reaction solution is subjected to post-treatment to obtain the products.

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.
