摘要

Sunlight-driven regeneration of nicotinamide adenine dinucleotide (NADH) is crucial for various enzymatic processes, redox reactions, and biological energy transfer mechanisms. However, developing highly effective and selective photocatalysts for NADH regeneration continues to pose significant challenges in contemporary research. In this study, we present a novel methodology for NADH regeneration utilizing a cadmium sulfide-based photocatalyst, specifically sulfur-oxygen doped graphitic carbon nitride, referred to as CdS@S-O-gC3N4. The CdS@S-O-gC3N4 photocatalyst exhibits exceptional charge transfer properties, coupled with an optimal optical band gap, which significantly enhances its ability to harvest sunlight effectively. These beneficial characteristics suggest that this photocatalytic system can efficiently facilitate NADH regeneration under solar irradiation conditions. Experimental results revealed a remarkable NADH regeneration yield of 59.48% within 90 min of solar light exposure, underscoring the catalyst’s high efficiency and potential for sustainable energy applications. Comprehensive characterization techniques, including UV-visible spectroscopy, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), and X-ray diffraction (XRD), were employed to analyze the structural and functional properties of the synthesized photocatalyst. These analyses confirmed the presence of critical functional groups and the material’s favourable morphology, contributing to its enhanced photocatalytic performance. Our findings highlight the CdS@S-O-gC3N4 photocatalyst as a highly effective candidate for NADH regeneration, representing a significant advancement in the field of photocatalysis. The results indicate that this innovative approach may pave the way for the development of efficient and sustainable methods for biochemical energy conversion, ultimately contributing to advancements in renewable energy technologies. Future research directions are suggested to further explore the stability and reusability of this photocatalytic system in practical applications.
