Abstract

MMoO4 (M = Fe2+, Co2+, Ni2+) nanocrystaline particles with similar nanoscale particle size were synthesized by a salt aqueous solution reaction. UV–Vis absorbance spectra show that the nanoparticles are of good light absorbance in UV–Vis light region and narrow band gap. The variation in oxidation–reduction potential (ORP) of selected methyl orange aqueous solution due to the presence of the nanoparticles is measured in various conditions. The light absorption and the ORP determine the photodegradation rate of the aqueous methyl orange solution on the nanoparticles. The ORP is clearly also a necessary and useful parameter in research on and applications of the photocatalysis.
