Polyoxometalates (POMS) are a wide class of well-defined, early transition metal-oxygen clusters with enormous structural characteristics and multiple functions, which can make a significant contribution to the material development for catalysis and photochemical reactions [1]. In recent years, polyoxometalates (POMs) have attracted particular interest in photocatalysis due to their strong Bronsted and their structural properties [2]. In this study, the removal and destruction of Methyl orange were examined with metal – organic hybrid of phosphotungstate -hexamine-nickel under sunlight irradiation. The effects of various experimental parameters were examined on the decolorization of Methyl orange. The results showed that this water insoluble hybrid is a good photocatalyst Methyl orange under solar light irradiation.
