39. Lignin as Photocatalysts

Lignin, a complex organic polymer found in plants, is gaining attention for its potential as a photocatalyst. This chapter explores the challenges and opportunities in modifying lignin to enhance its UV-shielding properties while reducing its color, which are influenced by its functional groups. The text delves into the role of lignin in photocatalysis, highlighting its potential for degrading pollutants and generating hydrogen from solar energy. It also discusses the use of lignin in various advanced oxidation processes and its potential for lignin valorization. The chapter emphasizes the importance of lignin's structure and sources, as well as its potential applications in environmental pollution remediation and agricultural applications. The text concludes with a discussion on the future prospects of lignin as a photocatalyst, highlighting the need for further research and development in this promising field.
