Black titanium dioxide (B-TiO 2 ) formed by surface disorder engineering has attracted great attention due to its narrowed band gap, enhanced visible-light absorption, and various applications in photocatalysis, hydrogen production, photothermal conversion, etc. The hybrid of B-TiO 2 with the other materials provides vast potential to improve it performance further. In this work, highly e cient visible-light-driven B-TiO 2 /activated carbon (AC) composite catalysts were synthesized by sol-gel method combined with argon heat treatment. The effect of AC content on the morphology, structure and optical properties of B-TiO 2 /AC was investigated. X-ray photoelectron spectroscopy (XPS) results showed a Ti-C-characteristic peak at 283.6 eV, which indicates the interaction between AC and B-TiO 2 . The photocatalytic experiments showed that the combination of 25wt% AC and B-TiO 2 exhibited remarkable and stable photocatalytic performance for removing Rhodamine B (RhB). Particularly, under visible light irradiation (λ>420 nm), 82% of RhB was degraded within 60 minutes, which is 16% higher than B-TiO 2 and 48% higher than white TiO 2 (W-TiO 2 ). Moreover, the RhB was degraded by 92% within 30 min under full-spectrum irradiation, which was 18% higher than B-TiO 2 and 61% higher than W-TiO 2 . This work proposed a green and lowcost method for developing B-TiO 2 based photocatalyst with improved performance. HighlightsThe composites showed excellent photocatalytic activity in removing pollutants.The enhanced visible light absorption, effective inhibition of electron-hole complexation and fast electron transfer endow the composites high catalytic performance.Black titanium dioxide prepared at 25% activated carbon doping showed the lowest bandgap energy.
