Synthesis, properties, and applications of Vanadium pentoxide (V2O5) as photocatalyst: a review
description Water pollution has increased worldwide, sparking interest in photocatalysis, a viable water treatment approach. Vanadium pentoxide (V2O5) is a good photocatalyst for photocatalytic degradation due to its excellent crystallinity, high yield and recyclability, low cost, photo-corrosion resistance, small band gap (2.3 eV), improved electron mobility, and broad absorption range. Pure V2O5‘s photocatalytic efficiency is limited by inefficient photonic and quantum processes, and its tiny structure enables photogenerated carriers to recombine, reducing efficiency. This prevents widespread use of V2O5. This mini-review examines V2O5 as a potent visible-light photocatalyst, focusing on its structure, synthesis methods, and modifications that improve its efficiency.
