Research and Application of Synthesis, Electrochemical and Photocatalytic of Polyaniline/H2Ti4O9 Nanocomposite Material

Aniline(ANI)/ H₂Ti₄O₉ is used as a precursor of Polyaniline(PANI)/H₂Ti₄O₉ layered nanocomposite, Polyaniline(PANI)/H₂Ti₄O₉ layered nanocomposite takes the aniline(ANI)/H₂Ti₄O₉ as a precursor, which is synthesized by in situ polymerization. The synthesis, morphology and structure of the composites were characterized by XRD, SEM, IR and TGA/DSC. Aniline is arranged in the interlayer of H₂Ti₄O₉ in a monolayer way with the benzene ring perpendicular to the laminate. The Polymerized Polyaniline molecules are arranged in the interlayer in a single layer. PANI/H₂Ti₄O₉ composites have excellent thermal stability, redox activity and visible light catalytic degradation of methylene blue activity. This study provides a new idea for the preparation of polyaniline based nanocomposites. This material has potential application prospects in electrochemical sensors and wastewater treatment.
