Photocatalytic degradation of methylene blue by TiO2 film and Au particles-TiO2 composite film

“…6 shows representative HPLC elution profiles for the degraded aqueous solution of MB at t = 120 min. From mass spectrometry, the peaks 1 to 6 can be attributed to 1 (MB), 2 (AB), 3-4 (AA or N, N' -dimethylthionin (the isomer of AA) [17][18][19]), 5 (AC), and 6 (Th). Both N, N'-dimethylthionin and AC are found to exist in the solution, though their concentrations are low.…”
