Key Parameters in Photocatalyst Design for Effective Textile Dye Degradation Through Designing MOF

This review examines the application of Metal-Organic Frameworks (MOFs) as solar-driven photocatalysts for efficiently removing textile dyes from water, with the goal of addressing current limitations in efficiency. It begins with a comprehensive examination of textile dyes, categorizing them based on their properties and molecular structures. The impact of these dyes on water quality is evaluated through chemical, physical, and molecular analyses. Subsequently, the review examines the application of photocatalysts, highlighting their potential in solar-driven processes. Detailed analyses of key parameters influencing photocatalytic efficiency, including band gap engineering, surface area, vacancies, recombination dynamics, active species, stability, electron flow, and absorptivity, are thoroughly explored. The discussion extends to the experimental conditions that can be manipulated to enhance efficiency, including dye concentration, photocatalyst dosage, solution pH, light source, and temperature. The review also encompasses the mechanisms underlying the photocatalytic actions of MOFs. The review serves as a foundation for examining existing research on using MOFs as photocatalysts for the removal of textile dyes under visible or sunlight irradiation. The concluding section provides a comprehensive summary of the field’s current state, offering insights into prospects that can bridge the gap between MOFs and practical applications in solar-driven photocatalysis for textile dye degradation.
