Abstract

Glucose, an abundant and renewable form of biomass, has garnered significant attention in research for its conversion into high-value chemicals such as gluconic acid. Traditional methods for biomass transformation typically involve high energy input, elevated temperature, pressure, and costly systems. In contrast, photocatalysis emerges as a promising approach to produce organic molecules under mild conditions, harnessing energy from natural sunlight or lamps. This study presents the nitrogen-enriched graphene with zeolite second Mobil�5 (NenG/ZSM-5) photocatalyst, evaluated for generating high-value chemicals (gluconic acid and leucodopaminechrome) under solar light irradiation. The NenG/ZSM-5 photocatalyst, synthesized from nitrogen-doped graphene and ZSM-5, successfully converted dopamine into leucodopaminechrome (71.54 ) � a critical step in dopamine regeneration and transformed glucose into gluconic acid (85 ). The addition of ZSM-5 to NenG provided stability and enhanced product selectivity. The outstanding performance of the NenG/ZSM-5 photocatalyst can be attributed to its heightened solar light harvesting potential, appropriate energy band gap, and uniformly arranged �-electron channels. This research focuses on solar conversion of glucose to gluconic acid and dopamine regeneration, with potential for further exploration in the research domain. © 2024 Wiley-VCH GmbH.
