Summary
Advanced materials that combine functionalization and hybridization strategies represent a pivotal frontier in materials science for addressing global environmental and energy challenges. Titanium dioxide (TiO₂) has long been recognized for its photocatalytic properties, chemical stability, and potential in energy-related applications. However, inherent limitations such as a wide band gap and rapid recombination of photogenerated charge carriers restrict its performance under visible light. Recent research efforts have focused on tailoring TiO₂ through functionalization and hybridization with bio-based components, polymers, carbonaceous materials, and metal or non-metal dopants, which significantly enhance light absorption, charge separation, and catalytic efficiency while aligning with principles of sustainability and eco-friendly design.
This Special Issue aims to bring together high-quality original research and review articles that advance the understanding, design, synthesis, characterization, and application of functionalized and hybrid TiO₂-based biomaterials for photocatalysis and energy applications. Contributions are encouraged that explore innovative material combinations and mechanisms that improve photocatalytic activity and address critical environmental and energy conversion challenges.
Potential topics include but are not limited to:
• Functionalization strategies to enhance TiO₂ photocatalytic performance
• Hybrid TiO₂ composite materials with biopolymers (e.g., cellulose, chitosan, lignin)
• Integration of TiO₂ with carbon-based materials and nanoparticles
• Visible-light active TiO₂-based systems for environmental remediation
• Photocatalytic water splitting and hydrogen production
Keywords
