Enhanced photocatalytic activity of Ba doped BiFeO3 by turning morphologies and band gap

Facile synthesis of pure BiFeO3 and Bi2Fe4O9 nanostructures with enhanced photocatalytic activity

“…Despite its less photocatalytic activity compared to Bi 2 Fe 4 O 9 , our as-grown BFO is efficient regarding other works such as the one presented by Li et al [56] who reported 40% of MB degradation after 3 h of solar irradiation using BiFeO 3 microcrystals synthesized by a controlled hydrothermal method, and also better than results obtained for doped BFO and BFO composites destined for photocatalytic activity such as a-Fe 2 O 3 /BiFeO 3 synthesized by Zhang et al using two-step hydrothermal method [57][58][59][60]. Our nanosized BFO therefore remains interesting as photocatalysis applications.…”

“…Our nanosized BFO therefore remains interesting as photocatalysis applications. Nanosized shape lowers the bandgap [59] causing larger absorption of sunlight. However, reducing particle sizes can also lead to an increase in macro strain and oxygen defects, which change the light absorption [61][62][63].…”

Role of cooperative factors in the photocatalytic activity of Ba and Mn doped BiFeO3 nanoparticles

“…37 Mn-doped BFO NPs were able to degrade acid red dye, and Ba doped BFO NPs was effectual to degrade MO dye. 38,39 The photodegradation of CR dye using Ba and Mn co-doped and Ca doped BFO nanobers was reported recently. 40,41 In spite of its calibre in photocatalysis, nanober production is difficult and not worthwhile for large-scale application.…”

Controllable synthesis and characterization of Mg2SiO4 nanostructures via a simple hydrothermal route using carboxylic acid as capping agent and their photocatalytic performance for photodegradation of azo dyes

“…It is conspicuous, in the proximity of light, that the photocatalyst can generate an electronhole pair in the conduction and valance band that effected degradation of contaminants. [40][41][42][43][44][45][46][47][48]…”
