WO3-Doped TiO2 Coating on Charcoal Activated with Increase Photocatalytic and Antibacterial Properties Synthesized by Microwave-Assisted Sol-Gel Method

Wo3-doped tio2 coating on charcoal activated (ca) was prepared by microwave-assisted sol-gel method. the samples calcined at the temperature of 500°c for 2 h with a heating rate of 10°c/min were characterized by xrd,eds,and sem. the photocatalytic and antibacterial activities of wo3-doped tio2 coating on ca were investigated by means of degradation of a methylene blue (mb) solution and against the bacteria e. coli,respectively. the effects of wo3 concentration were discussed. the 1% wo3-doped tio2 coated ca seems to exhibit the higher photocatalytic and antibacterial activity than other samples. the wo3-doped tio2 coated on ca are expected to be applied as a photocatalyst for water purification. © 2017 weerachai sangchay.
