Abstract

The current research work deals with the preparation of TiO2 and GO/TiO2 composite by simple, chemical, cost effective hydrothermal method. Graphene oxide (GO) is prepared by modified Hummer's method. Dispersion of GO is achieved by an ultrasonic cleaning bath for 1 h. using a power of 200 W and at a frequency of 40 kHz. The prepared catalyst material is characterized by different characterization techniques. XRD study confirms the prepared material is polycrystalline in nature. The synthesized TiO2 and GO/TiO2 photocatalyst materials are used to study the photocatalytic degradation of salicylic acid under sunlight illumination. GO/TiO2 composite shows superior photocatalytic activity than TiO2. GO/TiO2 composite shows 57% degradation of salicylic acid. Mineralization of salicylic acid is studied using chemical oxygen demand.
