Abstract

Orthorhombic vanadium pentoxide (V₂O₅) is the most stable oxidation state leading to its layered structure, increased stability, and electrochemically well-being. Using a cationic ligand, cetyltrimethylammonium chloride/CTAC, sheet-like V₂O₅ nanostructures (NSs) and those decorated with plasmonic silver nanoparticles (AgNPs) were synthesized hydrothermally, named as Ag/V₂O₅ nanocomposites (NCs). The XRD pattern was indexed to orthorhombic V₂O₅ phase, while XPS analysis showed the formation of reduced oxidation phase at material's surface due to electron beam-induced reactions under X-ray exposure. A strong relation between visible photoluminescence (PL) and structure of both samples was observed, and comparatively the weak PL intensity of Ag-anchored V₂O₅ NCs was attributed to staggered gaps at the interface, suppressing the charge-carriers recombination across interfaces. The photoelectrocatalytic activities of both samples, coated over FTO substrates, showed significantly enhanced photoelectrochemical properties of Ag/V₂O₅ NCs based photoanode fascinated by plasmonic silver, their increased surface area and greater separation of photogenerated charges at the interface.
