Microwave synthesized nanostructured TiO2-activated carbon composite electrodes for supercapacitor

► Nanostructure TiO2 has been prepared by a microwave assisted synthesis method. ► Microwave irradiation was varied with time duration on the formation of nanoparticles. ► TiO2-activate carbon show very good specific capacitance for supercapacitor. ► Electrochemical properties were studied on electroanalytical techniques.
