The study successfully prepared carbon-doped oxygen-deficient TiO2 fiber photocatalysts using organic components in the fiber precursor as carbon sources, improving light harvesting ability and inhibiting carrier recombination. The carbon-doped fibers showed excellent photocatalytic activity and cycling stability, with a degradation rate of 96.99% for X-3B under visible light irradiation.
The carbon-doped oxygen-deficient TiO2(C-TiO2-n)fiber photocatalysts were prepared by sol-gel method combined with centrifugal spinning technology and heat treatment under steam. The structure,compo. nent and properties of the C-TiO2-n fibers as well as the effect of carbon doping on the photocatalytic activity of C-TiO2-n fibers were investigated. The results confirm that the introduction of carbon into TiO2 can be realized using the organic components in the fiber precursor as carbon sources without the introduction of external car. bon sources. The introduction of carbon components effectively improved the light harvesting ability of photo. catalysts and inhibited the recombination of photoinduced carriers. In the photocatalytic degradation experi. ment with azo dye reactive brilliant red (X-3B)as the target pollutant,C-TiO2-n fibers showed excellent photo. catalytic activity and cycling stability. After visible light irradiation of 60 min,the degradation rate of X-3B over C-TiO2-n fibers reached 96.99%,and the kinetic constant was 0.0556 min(-1), 19.86 times higher than that of TiO2-n fibers.
