Dual Shield: Bifurcated Coating Analysis of Multilayered WO₃/BiVO₄/TiO₂/NiOOH Photoanodes for Sustainable Solar-to-Hydrogen Generation from Challenging Waters.

ABSTRACT: The heterostructure WO₃/BiVO₄-based photoanodes have garnered significant interest for photoelectrochemical (PEC) solar-driven water splitting to produce hydrogen. However, challenges such as inadequate charge separation and photocorrosion significantly hinder their performance, limiting overall solar-to-hydrogen conversion efficiency. The incorporation of cocatalysts has shown promise in improving charge separation at the photoanode, yet mitigating photocorrosion remains a formidable challenge. Amorphous metal oxide-based passivation layers offer a potential solution to safeguard semiconductor catalysts. We examine the structural, surface morphological, and optical properties of two-step-integrated sputter and spray-coated TiO₂ thin films and their integra
