Coinage metal (Ag, Cu) decorated BiFeO3 nanoparticles: synthesis, characterization and their photocatalysis properties

Photocatalytic performance of BiFeO3 based on MOFs precursor

“…Compared with other methods, the BFO prepared by this method exhibits better photocatalytic performance, as shown in Table 2. [30] 2 Microwave hydrothermal 2.08, 2.06 [31] 3 Hydrothermal 2.03-1.89 [32] 4 Solid state 2.30 [33] 1.82, 2.0 5 Sol-gel 2.35 [33] 6 Double solvent sol-gel 2.10 [34] 7 Hydrothermal 2.82 [9] Generally, smaller particles is expected to reduce the recombination opportunities of the photogenerated electron-hole pairs, and smaller band gap allow the formation of larger number of charges upon the same visible light irradiation. [5,29] These collectively lead to an increase in the photocatalytic activity.…”

“…The photocatalytic performance of BFO can be further improved by reducing the bandgap of BFO and increasing the degradation capacity of pollutants . To improve the photocatalytic performance of BFO, many schemes have proposed, such as decrease in grain size, transition metal ion doping, coupled semiconductor photocatalytic materials, and optimize preparation methods …”

“…[5] To improve the photocatalytic performance of BFO, many schemes have proposed, such as decrease in grain size, transition metal ion doping, coupled semiconductor photocatalytic materials, and optimize preparation methods. [6][7][8][9] At present, BFO is mainly prepared by the following methods, such as coprecipitation, hydrothermal method, automatic combustion method, ultrasonic method and so on. [10][11][12] However, these methods require high-temperature conditions or long-term preparation.…”
