Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger
