Performance of TiO2/Ag/CA for efficient adsorption of methylene blue

The incorporation of additives and inclusion of metal dopants on titanium dioxide (TiO2) could improve its inherent limitations and result in enhanced photocatalytic efficiency. In this work, the performance of TiO2/ Ag with the use of cellulose acetate (CA) was investigated for the degradation of...
