dc.description.abstract | Black colour TiO2 films were synthesized on amorphous fused silica substrates by DC magnetron sputtering technique with carbon powders placed at the working magnetron surface. Comprehensive sample analysis by X-ray diffraction, energy dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy showed that the rutile/anatase heterostructure TiO2 films were successfully formed. Moreover, observation of Osingle bondTisingle bondC bonds confirmed that TiO2 phase was doped by carbon additives. Scanning electron microscopy, atomic force microscopy and X-ray diffraction were used to identify the effect of deposition time and TiO2 film thickness on the surface morphology, roughness and crystallite size. Results of electron spin resonance showed that oxygen vacancies were generated on the surface with trapped unpaired electrons. Optical analysis by UV–vis light spectrophotometer showed that TiO2 films with carbon additives improve its capability to absorb visible light. Accordingly, methylene blue bleaching experiments under UVsingle bondA and visible light irradiation showed that black colour TiO2 films are capable to decompose methylene blue solution at both UVsingle bondA and visible light irradiation.----/ / /---- This is the preprint of the following article: Sarunas Varnagiris, Arturs Medvids, Martynas Lelis, Darius Milcius, Andris Antuzevics, Black carbon-doped TiO2 films: Synthesis, characterization and photocatalysis, Journal of Photochemistry and Photobiology A: Chemistry Volume 382, 1 September 2019, 111941 (2019), DOI 10.1016/j.jphotochem.2019.111941, which has been published at https://www.sciencedirect.com/science/article/abs/pii/S1010603019303442.
