摘要：
TiO2 was synthesized on biochar derived from wood waste assisted by ionic liquids (1-butyl-3-methylimidazolium chloride ([C(4)mim]Cl) and 1-butyl-3-methylimidazolium tetrafluoroborate ([C(4)mim][BF4])). We compared the effects of photocatalysts synthesized with [C(4)mim]Cl (Ti-WB-Cl) and [C(4)mim][BF4] (Ti-WB-BF4) on the degradation of methyl orange. Using XRD, the nanoparticles of anatase TiO2 in Ti-WB-Cl and Ti-WB-BF4 were formed. Within 120 min under UV, the 88.1 and 99.8% of methyl orange were degraded, respectively. Moreover, by-products were barely observed using Ti-WB-BF4 photocatalyst. By XPS spectra, the Ti-WB-BF4 with carbon and fluorine incorporation suggests that enhanced photocatalytic degradation of methyl orange had occurred. Graphic abstract
