文摘

Composite materials consisting of silver, titanium dioxide, and bamboo charcoal have been prepared from stepwise methods including sol-gel synthesis, wet impregnation, and electrochemical deposition. These as-fabricated composites are investigated for the possibility in multi-application that includes adsorption, photocatalysis, and anti-microorganism. Characterization methods such as scanning electron microscope, transmission electron microscope, gas adsorption, and X-ray diffraction are employed to prove the existence of all three components and their hybrid structure. The adsorption and photocatalysis are determined as the methylene blue molecules are removed continually under the absence and presence of 366 nm UV light. Bactericidal efficacy is also studied to demonstrate the disinfection potential for hygienic purpose.
