Used in photocatalytic applications for water splitting and CO₂ reduction due to its excellent light absorption in the visible range and high chemical stability. Its amino-functionalized structure enhances charge separation efficiency, making it effective for generating hydrogen under visible light. Also employed in environmental remediation to degrade organic pollutants such as dyes and pharmaceuticals. Shows promise in gas adsorption and separation processes, particularly for CO₂ capture from flue gas or air. Investigated for use in sensing applications and as a support material for metal nanoparticles in heterogeneous catalysis.
