Influence of carbon content and irradiation modes on the antibiotic removal from water using VIS-activated TiO/expanded graphite composite photocatalysts.

TiO/expanded graphite (TiO/EG) composite films were applied to water treatment for sulfadiazine (SDZ) degradation in a continuous flat plate photochemical reactor. The films were synthesized by sol-gel method and deposited on borosilicate glass by airbrush spray coating technique, forming a TiO/C heterojunction. Increasing the amount of carbon promoted more efficient photocatalytic removal of SDZ under simulated sunlight, which increased from 9.

VIS-active TiO films decorated by expanded graphite: impact of the exfoliation time on the photocatalytic behaviour.

TiO/C nanocomposite films were applied on water treatment. Expanded graphite nanosheets (EG) were obtained by UVC-assisted liquid-phase exfoliation technique, without the addition of acids, surfactants, or aggressive oxidizing agents, which characterizes the process as an eco-friendly method. The carbon nanosheets were synthesized directly from graphite bulk at different times and deposited on TiO films surface by airbrush spray coating method, forming a TiO/C heterojunction.
