A facile preparation of nanosized Zno and its use in photocatalytic decolorization of methyl orange

Nanoparticles zinc metal was prepared by a simple electrochemical method of a N,N-dimethylformamide solution containing 0.1M tetraethylammonium perchlorate in the presence of naphthalene as a mediator in a one-compartment cell fitted with a platinum plate cathode and a zinc plate anode at 60 mA/cm2...
