Highly Efficient Photocatalytic Z-Scheme Hydrogen Production over Oxygen-Deficient WO_3-x Nanorods supported Zn_0.3Cd_0.7S Heterostructure.

ABSTRACT: The demand for clean renewable energy is increasing due to depleting fossil fuels and environmental concerns. Photocatalytic hydrogen production through water splitting is one such promising route to meet global energy demands with carbon free technology. Alternative photocatalysts avoiding noble metals are highly demanded. Herein, we fabricated heterostructure consist of oxygen-deficient WO_3-x nanorods with Zn_0.3Cd_0.7S nanoparticles for an efficient Z-Scheme photocatalytic system. Our as obtained heterostructure showed photocatalytic H₂ evolution rate of 352.1 μmol h^-1 with apparent quantum efficiency (AQY) of 7.3% at λ = 420 nm. The photocatalytic hydrogen production reaches up to 1746.8 μmol after 5 hours process in repeatable manne
