Synthesis and modification of nickel hydroxide particle synthesized by self-assembly and electron beam irradiation technique for photocatalyst activity

The purpose of this work is to study the methyl orange removal of Ni(OH)2 nanoparticles. The photo-catalyst activity is investigated based on UV lamp of 18 watt. Ni(OH)2 is synthesized by a self-assembly process and then exposed to electron beam radiation at 10 MeV energy with various doses ranging from 50 kGy to 500 kGy. The properties of Ni(OH)2 nanoparticles are then evaluated. No significant change of functional group and percent of crystallinity are observed. The morphology is uniformly presented as a plate-like. The specific surface area, pore size and pore volume are reduced. Point of zero charge confirmed that positive charge is presented onto the surface. It therefore provides strong affinity to negative charge of dye removal. As-synthesized Ni(OH)2 particle exhibits the excellent properties for methyl orange adsorption and photocatalyst activity over methyl orange degradation. It was remarkable to note that Ni(OH)2 particle is therefore considered as an excellent candidate for dye degradation in textile industry.
