Dual-functional photocatalysis: bridging hydrogen production and environmental remediation – a review

Key Points

• This review explores the role of solar-driven photocatalysis in producing hydrogen and removing organic pollutants from wastewater.
• Reviewed solar-driven photocatalytic processes for H2 production and organic pollutant degradation.
• Discussed the use of contaminants as sacrificial donors in wastewater treatment.
• Explored implications for circular economy in environmental processes.
• Identified effective photocatalysts for simultaneous H2 production and pollutant removal.
• Emphasized improved efficiency in wastewater treatment through circular economy principles.
