Photocatalytic activity of anatase-brookite TiO2 nanoparticles synthesized by sol gel method at low temperature

TiO2 photocatalysis is widely used in a variety of applications and products in the environmental and energy fields, including self-cleaning surfaces, air and water purification systems, sterilization, hydrogen evolution, and photoelectrochemical conversion. In this paper TiO2 nanoparticle was investigated for the degradation of Rhodamine B (RhB) under UV light. Nanocrystalline Anatase-Brookite TiO2 catalyst was synthesized via sol-gel method using the Titanium tetraisopropoxide (TTIP) at a temperature of 50 °C under mild conditions. XRD, TEM, SEM, FT-IR and BET were applied to characterize the crystal phase. The Crystalline size of TiO2 powder has been obtained with diameter <30 nm at 500 °C using an acid. The photocatalytic activity of TiO2 nanoparticle show that the degradation of Rhodamine B under UV light have removal of 95% dye was degraded in 60min.
