摘要： A new heterogeneous catalyst for various organic oxidation processes and a method of making the same by a successful immobilization of a copper (II) bis-Schiff base hydrazone complex on the surface of a composite ZnO—TiO2 to afford as active catalyst CuL2Cl2@ZnO—TiO2. This novel catalyst can be used to selectively oxidize benzyl alcohol to benzaldehyde.

摘要： A method of forming TiO2—ZnO nanoparticles coated by a copper (II) complex includes forming a mononuclear copper complex by treating a ligand with Cu2+ ions; and immobilizing the mononuclear copper complex on TiO2—ZnO nanoparticles to obtain the TiO2—ZnO nanoparticle coated by the copper (II) complex. The TiO2—ZnO nanoparticles coated by a copper (II) complex thus produced have improved catalytic effectiveness and increased efficiency by reducing catalytic reaction time and temperature, particularly in methods of catalyzing oxidation of an alcohol or of catalyzing decarboxylative bromination of an acid.
