Bismuth doped zno/moo2 composites for the catalytic degradation of methylene blue

From past years, the demand of clean water has been increased due to shortage of portable fresh water. Parallel, the use of composite materials for the catalytic degradation of pollutants particularly dyes in industrial effluents has attracted good attention. In this work, bismuth doped ZnO/MoO2 composites were synthesized by co-precipitation method using bismuth chloride, zinc sulphate and sodium molybdate as starting precursors. The structural/morphological studies of these composites were accomplished by UV–Visible spectroscopy, Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy. The catalytic activity of the bismuth doped ZnO/MoO2 composites was investigated by degradation of methylene blue (MB) dye. The degradation of MB was observed to be 75% at only 45 sec and enhanced catalytic activity was observed by increasing Bi content in synthesized composites.
