Bi-Fe oxides are stable materials with potential photocatalytic activity under solar light photons. So far, however the of pure-phase nanosized mullite-Bi2Fe4O9 has not been studied. Usually, synthesis is hampered by co-formation perovskite BiFeO3. Herein we demonstrate that nanoparticles prepared Flame Spray Pyrolysis (FSP) technology highly efficient O2 production photocatalysts, achieving &g...

Increasing the content of anion vacancies may yield significant improvement in overall electrochemical energy-storing performance perovskite materials, where vacancy sites act as highly favorable ion diffusion paths. However, a detailed study on energy storage mechanism at binary cation under deficiency should be further explored supercapacitor electrode materials. In this study, simple hydroth...

Free-standing BiFeO3 perovskite particles with a size ranging from polycrystalline bulk down to 5 nm have been studied by high-energy resonant (Bi K edge) x-ray diffraction coupled to differential atomic pair distribution function analysis. Nanosized BiFeO3 particles are found to exhibit extra, i.e., beyond the usual thermal, structural disorder that increases progressively with diminishing the...
