N2 - Ni-Pd, and Ni-Pd supported on zirconia (Ni-Pd/ZrO2 ) nanoparticles (NPs) were prepared via the co-precipitation method. The morphological study illustrated that the Ni-Pd NPs were well deposited in a dispersed form on the surface of ZrO2 having a size below 100 nm. The formation of Ni-Pd was also confirmed by energy-dispersive X-ray spectroscopy and X-ray diffraction. The microwave-assisted (MW) catalytic degradation of the Acid Orange-8 (AO-8) was carried out at various parameters, that is, microwave intensity, dye concentrations and catalyst dose. Hydrogen peroxide was used as a precursor of hydroxyl radical. The optimized conditions for MW catalytic degradation of AO-8 (maximum; 98.8%) in the presence of H2 O2 were set as microwave (500 W), concentration (0.0001 M) and catalyst (0.05 g). The degradation was monitored by a UV-Visible spectrophotometer at regular intervals of time. The study revealed the industrial scale applicability of the catalysts for colored wastewater treatment.
