Dandelion-Like CuWO₄/WO₃ Composite Photoanode Employing Layered Double Hydroxide Catalysts for Enhanced Photoelectrochemical Water Oxidation.

ABSTRACT: This study introduces a novel modified dandelion-like CuWO₄/WO₃ heterojunction photoanode featuring NiCo-layered double hydroxide (NiCo-LDH) as a co-catalyst, fabricated through hydrothermal and drop casting methods. Morphological and photoelectrochemical assessments elucidate that the optimal dandelion-like CuWO₄/WO₃ heterojunction facilitates charge separation in a neutral solution. Additionally, electrochemical evaluations of the CuWO₄/WO₃ heterojunction decorated with LDHs co-catalysts reveal enhancements in photon-to-current conversion efficiency (IPCE), cathodic shift of the photocurrent onset potential, and an increase in photocurrent density to 0.17 mA cm^-2 at 1.23 V vs. RHE, which is twice that of the pri
