“…Photocatalysts based on semiconductor materials can produce photoproduction electron which has strong reducibility and hole with strong oxidizability under the irradiation of visible light, which contribute to the conversion of organic pollutants and inorganic pollutants into harmless substance [5,6]. Up to now, numerous efforts have been strived to develop efficient photocatalysts, such as Ag 3 PO 4 [14,15], g-C 3 N 4 [16], BiFeO 3 [17], BiVO 4 [18], and BiOI [19].…”
