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 The production of new solar fuel through CO photocatalytic reduction has aroused tremendous attention in recent years because of the increased demand of global energy sources and global warming caused by the mass concentration of CO in the earth's atmosphere. In this work, UiO-66-NH was co-modified by the Au nanoparticles (Au-NPs) and Graphene (GR). The resultant nanocomposite exhibits a strong absorption edge in visible light owing to the surface plasmon resonance (SPR) of Au-NPs. More attractively, Au/UiO-66-NH /GR displays much higher photocatalytic activity (49.9 μmol) and se...
