Abstract：

SO42-　/TiO2　solid　acid　was　used　for　photocatalytic　degradation　of　CH3Br,　and　its　photocatalytic　activity　is　2　∼　10　times　higher　than　that　of　TiO2　under　the　same　reaction　conditions.　The　SO42-　/TiO2　sample　impregnated　with　H2SO4　solution　(1　mol/L)　is　of　superacidity　(H0<　-12.14),　possessing　the　highest　acid　strength　and　the　highest　photocatalytic　activity　for　degradation　of　CH3Br.
