Hydrogen (H2) production through water splitting using sustainable energy sources is gaining increasing attention. However, limited catalytic performance based on a single driving force presents both opportunities and challenges for achieving a high-efficiency H2 output. Exploring multiple driving sources to enhance the comprehensive catalytic performance shows great promise. BiFeO3 (BFO), with features of narrow band gap and ultrahigh ferroelectric polarizations, is considered as a promising alternative candidate for green H2 production from water splitting. However, the inherent overpositive...

Very recently, the ferroelectric photovoltaic effect of multiferroic BiFeO3 (BFO) has attracted much attention because of its large photovoltage beyond the bandgap and unique photocurrent switchable characteristics. However, the poor short-circuit current density (JSC ∼ μA/cm2) of BFO leads to a low power conversion efficiency (PCE), which greatly hinders its application and development as photovoltaic or optoelectronic devices. In this paper, a novel heterostructure comprised Au nanoparticles layer and BiFe0.9375Mn0.0625O3 (BFMO) thin film was constructed. The results and analysis showed t...

Abstract Bismuth ferrite (BiFeO ) has recently become interesting as a room-temperature multiferroic material, and a variety of prototype devices have been designed based on its thin films. A low-cost and simple processing technique for large-area and high-quality BiFeO thin films that is compatible with current semiconductor technologies is therefore urgently needed. Development of BiFeO thin films is summarized with a specific focus on the chemical solution route. By a systematic analysis of the recent progress in chemical-route-derived BiFeO thin films, the challenges of these films are...
