Abstract: The NiO–CeO2 nano-catalysts, prepared by co-precipitation were investigated in catalytic wet air oxidation of paper industry wastewater. The structural, micro-structural and textural properties of catalysts were studied by XRD, FT-IR, N2-sorption, TGA, FE-SEM, TEM and EDS techniques. The prepared NiO–CeO2 nano-catalysts exhibited good activity at mild operating conditions of 90 °C and 1 atm. The catalytic activity was found to be increased with increasing Ni content, and the maximum removal efficiency (COD, 62%; color, 75%) was obtained with Ce40Ni60 nano-catalyst. The increased biodegradability from 0.27 to 0.42 proved the feasibility of CWAO in degradation of non-biodegradable compounds. The overall reactions during CWAO were found to follow the first order kinetics in terms of COD and color removal. © 2015 by American Scientific Publishers All rights reserved.
