Abstract

Recently, catalysis using single atoms has been gaining attention from the scientific community, due to its unique ability to resemble homogeneous complexes on solid supports. Among the main supports for single atom stabilization are doped carbons, graphenes and carbon nitrides. The latter stands out for the possibility of controlling the amount of metal as well as having a simple and effective synthesis. Crystalline carbon nitrides, in the form of poly(heptazine imide), are ideal supports for the coordination of isolated metal atoms. The presence of such single atoms has already been evidenced in oxidation reactions, especially the oxidation of benzene, which is quite challenging due to the stability of this molecule. Therefore, this project plans the application of catalysts with transition metal single atoms in crystalline carbon nitrides for the selective oxidation of benzene to phenol.
