Single BiFeO3 and mixed BiFeO3/Fe2O3/Bi2Fe4O9 ferromagnetic photocatalysts for solar light driven water oxidation and dye pollutants degradation

Single-phase BiFeO3 and BiFeO3–Fe2O3 nanocomposite photocatalysts for photodegradation of organic dye pollutants

“…Due to the difficulty in recovering the photocatalysts from the majority of the treated solution and reusing them, it is challenging to bring composite photocatalysis to the practical application. Nano and microparticles with a large surface area possess high photocatalytic activity [1][2], allowing a better spreading in an aqueous media [3]. They efficiently pass the light needed for the catalysts to be photoactivated.…”

“…Nano and microparticles with a large surface area possess high photocatalytic activity, 1,2 allowing better spreading in aqueous media. 3 They efficiently pass the light needed for the catalysts to be photoactivated. However, recovering those tiny particles through ltration or centrifugation typically results in higher operating costs for photocatalyst reuse in subsequent cycles.…”

“…Furthermore, it is possible to combine properties, such as ferroelectricity or piezoelectricity, with the photocatalytic effect to improve photocatalytic activity. The perovskite photocatalysts can be classified into the following categories: titanates, SrTiO 3 112–118 and BaTiO 3 119–123 ; tantalates, LiTaO 3 , 124 NaTaO 3 125–132 and KTaO 3 133–137 ; niobates, LiNbO 3 , 138,139 NaNbO 3 140–147 and KNbO 3 148–153 ; vanadates, AgVO 3 154–162 ; and ferrites, LaFeO 3 , 164–169 BiFeO 3 170–176 and GaFeO 3 177 . These compounds show great potential for application in visible light‐driven photoreactions.…”

“…However, the high recombination rate of photoexcited electron–hole (e − -h + ) pairs in bare BFO seriously limits its further application in the photocatalytic field. To overcome this problem, several modification strategies, including decoration with noble metals and creation of type-II heterojunction with other semiconductors, have been developed to promote the separation of photogenerated charges [17,18,19,20,21,22]. Although the recombination of photogenerated charges can be suppressed through the above methods, the redox ability of photogenerated electrons and/or holes could be more or less weakened simultaneously [23,24].…”
