Chitosan (CS) films containing visible light absorbing TiO2 nanoparticles modified with tungstophosphoric acid (TPA-TiO2) at different TPA-TiO2:CS ratios (10%, 20%, 30% and 40% (w/w) called CS/TPA-TiO2-10, CS/TPA-TiO2-20, CS/TPA-TiO2-30, and CS/TPA-TiO2-40 respectively) were prepared. Films were characterized by DRS, SEM-EDS, XRD, ATR-FT-IR, and contact angle (CA). Materials were evaluated in malachite green (MG) photobleaching solid-gas interface reactions upon different wavelengths.
