Abstract

Exploiting metal chalcogenide-based photocatalysts has fascinated researchers as a source of green hydrogen (H₂) energy. Herein, we have designed a novel selenium-enriched NiSe_1+x/ZIS (NiSe_xZ) photocatalytic system via a two-step hydrothermal and facile photo-deposition method. It was fascinating to conclude here that the NiSe_xZ photocatalytic system showed boosted H₂ evolution results in comparison with other sulphur-enriched NiS_1+x/ZIS (NiS_xZ) and tellurium-enriched NiTe_1+x/ZIS (NiTe_xZ). The optimized NiSe_0.5Z composite exhibited a photocatalytic H₂ evolution of 3.24 mmol g^-1 h^-1, a 9.8-fold increase over pure ZIS and it demonstrated an apparent quantum efficiency (AQE) of 2.06 % via 420 nm filter. Moreover, sulphur (S), selenium (Se), and tellurium (Te) synergistic active sites were exposed to promote H₂ evolution reaction in this work. Given the significant advancements and commendable performance exhibited by the Se-H_ads across the week bond, it is extremely probable that the NiSe_1+x cocatalyst holds immense potential for the development of sophisticated photocatalytic materials.
