In this work we study the influence of grain and particle size on structural optical properties BiFeO3 (BFO) nanoparticles resulting photocatalytic activity. Unexpectedly, activity is found to decrease while expected surface reaction area increases by decreasing particles size. We show that global structure, polarization, morphology, band gap are only weakly altered, if at all, some features, namely, Urbach energy low-energy bands, in absorption spectra substantially changed. argue these...
In this paper, we show that a pure single phase by doping Fe-site of BiFeO3 (BFO) using tetravalent Zr4+ ions can be achieved introducing cation (Bi3+) vacancies. The structural analysis reveals the ferroelectric nature BFO should weakly affected 10% as c/a ratio and Curie temperature TC remain roughly unchanged compared to BFO. contrast, magnetic properties are weak ferromagnetism change Néel TN observed. Beyond double-exchange interactions arising from creation Fe2+, propose another simple...
A-MnO<sub>2</sub> has the best adsorption capacity for methyl orange among other manganese oxide materials.
The surface plasmon resonance (SPR) of silver nanoparticles can be tuned throughout the visible and near-infrared region by their shape size. Considering SPR applications, an easy controllable method for preparing nanocrystals with defined size, is necessary. In this work, triangular nanoplates were synthesized reducing Ag(+) ions ascorbic acid in presence seeds poly(vinylpyrrolidone) (PVP) at room temperature. Both (as nucleation sites) PVP capping reagent) played important role determining...
Very recently, the ferroelectric photovoltaic property of bismuth ferrite (BiFeO3, BFO) has attracted much attention. However, physical mechanisms for its anomalous effect and switchable are still largely unclear. Herein, a novel design was proposed to realize high output in BiFeO3 films by manipulating oxygen vacancy concentration through alteration Bi content. Subsequent results analysis manifested that highest achieved Bi1.05FeO3 films, differing 1000 times from Bi0.95FeO3 films....
To overcome the bottleneck of water splitting, exploration efficient, selective, and stable oxidation catalysts (WOCs) is crucial. We report an all-inorganic, oxidatively hydrolytically WOC based on a polyoxometalate [(A-α-SiW9 O34)2Co8(OH)6(H2O)2(CO3)3](16-) (Co8 POM). As cobalt(II)-based cubane catalyst, Co8POM embeds double Co(II)4O3 cores. The self-assembled catalyst similar to oxygen evolving complex (OEC) photosystem II (PS II). Using [Ru(bpy)3](2+) as photosensitizer persulfate...

An applied stress field ${\ensuremath{\sigma}}_{3}$ can reversibly change the temperature of an elastocaloric material under adiabatic conditions, and $\ensuremath{\Delta}{T}_{{\ensuremath{\sigma}}_{3}}$ is usually maximized near phase transitions. Using a thermodynamic approach, we demonstrate that strength $\ensuremath{\alpha}=|\ensuremath{\Delta}{T}_{{\ensuremath{\sigma}}_{3}}|/|{\ensuremath{\sigma}}_{3}|$ 0.016 K/MPa be achieved benefiting from full first-order transition in...
Barocaloric effect in BaTiO3 single crystal is studied by a thermodynamic phenomenological model. It demonstrated that giant barocaloric can be achieved near room temperature with an adiabatic change of more than 3 K and span about 50 K. As expected, the electrocaloric peak shifted towards pressure. However, slight reduction found contrast to relaxor ferroelectrics LiNbO3. We believe our findings could open potential route combining pressure-mediated for cooling devices.
Coupling oxygen vacancy gradient distribution and flexoelectricity for the enhancement of ferroelectric photovoltaic effects.
Silver oxides (Ag2O and AgO) have attracted increasing attention as potential solar cell materials for photovoltaic devices due to their ideal bandgap non-toxicity. In order eliminate the complicated synthesis harsh reaction conditions (e.g. high temperature, vacuum, energy input, electron beam instrumentation) required by most synthetic strategies, we developed a very facile dry chemical approach directly prepare AgxO species on ITO substrate taking advantage of UV-O3 surrounding in...
Rare-earth ions (RE = La3+, Nd3+, and Er3+) substituted BiFeO3 (BFO) ceramics were synthesized by a conventional solid-state sintering procedure. X-ray diffraction patterns Raman spectra confirm rhombohedral R3c symmetry in all samples with significant distortion FeO6 octahedron, as well the occurrence of remarkable spin-phonon coupling notable change magnetic transition temperature induced RE dopants. The enhanced magnetization was observed RE-doped BFO ceramics, unveiling that spatial spin...
