Authors:     Dang Bao Trung, Hong Thien Luan, Nguyen Thien Phuc, Nguyen Ngoc Hanh
Abstract:    Copper nanoparticles were synthesized using nanocellulose as a reductant and also a support. The catalyst was characterized using X-ray diffraction (XRD), Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), transmission electronic microscopy (TEM) and atomic absorption spectrophotometry (AAS). Copper nanoparticles supported on nanocellulose (CuNPs/NC) effectively catalyzed the selective oxidation of cyclohexane using hydrogen peroxide as oxidant under mild conditions. Besides, the effects of catalyst concentration, temperature, reactant molar ratio, reaction time on the reaction conversion and product selectivity were also investigated. The optimal conversion was obtained at room temperature with total yield of 63% after 24hrs. No leaching of active copper species into the reaction solution was found. The catalyst could be reused several times with minimal loss of catalyst activity.
