Titanium dioxide (B)/glass fiber cloth (B-T/GFC) composites with photothermal enhanced photocatalytic properties were prepared by using a facile chemical synthesis and Sol-Gel method, using the glass fiber cloth and TiH 2 as substrate and precursor, respectively. XRD, SEM and TEM were employed to investigate the composition, structure and morphology of B-T/GFC composite. Different properties of the materials were studied by spectrophotometer, optical contact angle measuring instrument and solar simulator. The results show that the composite surface is composed of anatase black TiO 2 with a disordercoating of about 1 nm. Meanwhile, the B-T/GFC composite with high hydrophobicity has strong absorption ability in the wavelength range from 250 nm to 2000 nm. Compared with glass fiber cloth, the B-T/GFC composite reveals better photothermal ability under sunlight with one solar intensity (1 kW/m 2). The photocatalytic degradation ability of B-T/GFC composite in organic pollutants cutting waste solution is better than those of pure black TiO 2 (B-T) and P25. After irradiation for 2 h, the degradation of COD over B-T/GFC composite is about 1.3 times higher than that of P25. The B-T/GFC composite possessing excellent photothermal enhanced photocatalytic properties performance may lead to a range of novel applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
