Summary: BiVO4 is synthesized without any surfactant using bismuth nitrate pentahydrate and ammonium metavanadate through a simple reflux condensation method. The effect of different ratios of bismuth nitrate pentahydrate to ammonium metavanadate (1:1, 1:2, 2:1) on the structure and activity of BiVO4 is investigated. Various analytical techniques including XRD, BET, FE-SEM, and XPS are used to analyze the obtained BiVO4 nanomaterial, which shows spherical morphology, high porosity, and monoclinic scheelite crystalline phase. The nanoparticles prepared with a 1:1 ratio exhibit smaller size and higher photocatalytic efficiency in the degradation of crystal violet dye (CV) under visible light irradiation. Additionally, the prepared nanoparticles demonstrate good antibacterial properties.

This study successfully synthesized NiFe2O4@CoFe2O4 core-shell nanoflake arrays on a flexible stainless steel mesh using a simple and low-cost two-step chemical bath deposition method. The resulting electrode exhibited a quick electron/ion transfer and higher electrical conductivity due to the synergistic influence between NiFe2O4 and CoFe2O4 nanoflakes. The NiFe2O4@CoFe2O4 core-shell nanoflake array electrode demonstrated superior electrochemical performance, including a capacitance of 1459.4 F g-1 at a current density of 4 mA cm-2, excellent cycling stability with 85% retention over 5000 cycles at a high current density of 20 mA cm-2, and a high energy density of 21.15 W h kg-1 at a power density of 0.466 k W kg-1. The unique hierarchical structure of this novel integrated nanoarchitecture enables efficient ion and electron transport, a high number of active sites, and a synergistic impact, making it a promising candidate for improved electrodes in high-performance supercapacitors.
