Significant enhancement in the visible light photocatalytic properties of BiFeO₃–graphene nanohybrids

Facile synthesis of WO3 nanorods/g-C3N4 composites with enhanced photocatalytic activity

“…To overcome this demerit, many efforts have been made to improve the visible-light photocatalytic activity of TiO 2 , such as doping [10][11][12], co-catalyst loading [13] and so on [14,15]. Despite these tremendous achievements, a number of issues still need to be addressed and it is very important to explore new nontoxic photocatalysts with excellent visible-light catalytic activity [16,17].…”

Synthesis of g-C3N4/Ag3VO4 composites with enhanced photocatalytic activity under visible light irradiation

“…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].…”

Enhanced visible-light activities of porous BiFeO3 by coupling with nanocrystalline TiO2 and mechanism

“…To overcome these shortfalls and to improve the photocatalytic performance of BFO, elemental doping, fabricating with semi-conductor metal oxides and synthesis of porous perovskite oxides with larger surface area are highly desirable [8][9][10][11]. As we know that, catalysis belongs to the class of surface reaction and there should be a good contact between the catalyst's surface and the substrates [12].…”
