V₂O₅ -doped NiFe-layered double hydroxides: bifunctional catalysts for energy and environmental remediation

Addressing the dual challenges of sustainable energy production and environmental remediation, this research focuses on the development of V₂O₅-doped NiFe-layered double hydroxides (LDHs) for efficient water splitting and photocatalytic degradation of tetracycline. Utilizing a hydrothermal synthesis method, V₂O₅-doped NiFe-LDHs were successfully fabricated. The incorporation of V₂O₅ aims to enhance the catalytic performance by introducing additional redox-active sites, boosting electronic conductivity, and stabilizing the LDH structure during operational cycles. Comprehensive characterization, including X-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy, was employed to analyze the structural and morphological properties of the synthesized materials. Electrochemical studies demonstrated significant improvements in water splitting performance, including reduced overpotentials and enhanced hydrogen evolution rates. Additionally, the photocatalytic activity of V₂O₅-doped NiFe-LDHs for tetracycline degradation was evaluated, showing promising results for effective pollutant removal. These findings underscore the potential of V₂O₅-doped NiFe-LDHs as advanced materials for both clean energy production and environmental cleanup.
