About

I am a regular faculty member of the Institute of Chemical Sciences, University of Peshawar. I received my PhD degree from the Institute of Chemistry of Sao Carlos (IQSC), University of Sao Paulo (USP) Brazil in 2014 and Master degree (M.Sc) in analytical chemistry from University of Peshawar-Pakistan in 2006. My research focusses on the development of visible light active nanometric semiconductor photocatalysts, ORMOSIL-polyoxometalates hybrid photoactive materials, thin photoactive/self-cleaning films preparation, core@shell nanoparticles, organic-inorganic hybrid materials, sol-gel chemistry, water purification, photochromism and photocatalysis
