photocatalyst activity of a phosphotungstice acid organic hybrid for decolorization of ethylene blue in under solar light

In the environmental technology sector, industrial wastewater treatment is gaining importance for the removal of organic pollutants. large amounts of organic pollutants consumed in the industries are being released into the ecosystem over the past few decades and they constitute a serious threat to the environment [1]. organic and inorganic hybrid solid materials have been a contemporary theme of research since the 1990s, as a result of their use and applications in multidiscipline areas [2]. thanks to their distinctive nanoscale structures and excellent acid/base or redox properties, are long-studied for the design and construction of functional hybrid materials [3]. in this study, we describe a facile preparation of hybrid materials as effective photocatalysts by means of the usage of hexamine (hmt) to assemble with phosphotungstice acid (pta). a water insoluble (hmt-pta) hydrid has been synthesized as a light active photocatalyst. the catalyst shows a good photocatalytic activity towards the decolorization of methylene blue (mb) under solar light irradiation. the effects of various experimental parameters have been investigated on the decolorization of mb.
