  • Abstract

    We have investigated the photocatalytic degradation of brilliant red, an azo textile dye in the presence of CaMgO2 nanoparticles under natural sunlight. Complex metal oxide nanoparticle CaMgO2 was synthesized by solution combustion method. Its band gap energy, particle size and morphology were studied by absorption spectra, XRD and SEM. We have examined the photocatalytic activity of these nanoparticles on Brilliant red dye by varying pH, amount of catalyst, dye concentration etc.
