Visible-light-active bamboo biochar/TiO2 composites were fabricated by the calcination method using C16H36O4Ti as the titanium source and bamboo powder with different sizes as the carbon source. The TiO2 nanoparticles were observed to disperse onto the surface of bamboo biochar fiber. The sizes of the bamboo powder played an important role in the microstructures and the properties of bamboo biochar/TiO2 composites. The bamboo biochar/TiO2 composites displayed the photocatalytic activities both under visible light irradiation and UV irradiation. The adsorption isotherms better fitted Freundlich isotherm models and the photodegradation reactions followed pseudo-first-order kinetics. Bamboo charcoal/TiO2 composites exhibited high stability after up to four cycles. This research could pave the way for high-value applications of biomass in the environmental field. View Full-Text
