The presence of nitro compounds and such commercial dyes as Congo red, methylene blue, methyl orange and methyl red in water/wastewater causes environmental issues. The treatment of such industrial contaminants, new efficient hybrid catalysts are designed by Research groups all around the world. For this aim, a large of catalyst systems were designed and their water treatment capacities were investigated. As a part of Green Chemistry approach, food wastes could be used for production of porous carbon materials. In this work, a palladium/activated carbon hybrid catalyst (AC-Pd) was prepared and characterized by XRD, SEM/EDS and TEM. It was found from TEM analysis that the average particle size of AC-Pd hybrid was about 54 nm. The reduction capacity of AC-Pd for nitroarenes and organic dyes was investigated by UV-Vis. spectroscopy in aqueous media. According to catalytic tests results, AC-Pd nanocatalyst could be used in reduction of both nitro compounds and organic dyes.
