Adipic acid (hexadioic acid) is a bulk chemical presently produced using highly polluting processes. Herein, we discuss the catalytic evaluation of CuNPs on a hybrid PLA/TiO2 particle brush in the selective liqud-phase oxidation of cyclohexene to adipic acid using H2O2 as green oxidant. Various reaction conditions including effect of solvent, temperature, time and catalyst concentration were optimized in the reaction protocol. The recyclability as well as the stability of the catalyst was studied and a mechanism proposed for the observed results. Products and reaction evolution was tracked by GC–MS, 1H NMR and FT-IR.
