The direct or indirect discharge of organic pollutants causes serious environmental problems and endangers human health. high electron–hole recombination rate greatly limits the catalytic efficiency traditional TiO2-based catalysts. Therefore, starting from low-cost activated carbon (AC), a photocatalyst (F-Si-TiO2/AC) comprising fluorine (F)- silicon (Si)-doped TiO2 loaded on AC has been developed. F-Si-TiO2/AC porous structure. nanoparticles were uniformly fixed surface pores AC, producing many sites. band gap is only 2.7 eV. In addition, exhibits an excellent adsorption capacity toward methyl orange (MO) (57%) in dark after 60 min. Under optimal preparation conditions, showed significant photodegradation performance MO, reaching 97.7% irradiation with visible light for 70 Even under action different anions cations, its degradation lowest, at 64.0%, which good prospects practical application. At same time, long-term, stable, application potential can be easily recovered solution. this work provides new insights fabrication low-cost, porous, activated, carbon-based photocatalysts, used as high-performance photocatalysts pollutants.
