[Abstract]

　Catalyic decomposition of CFCs was investigated. The chemical reactions studied in this project are hyrolysis and oxidative decomposition. The most active catalyst for hydrolysis is TiO₂-ZrO₂ and that for oxidative decomposition is WO₃/Al₂O₃-ZrO₂. Surface properties and reaction mechanisms were also elucidated.
