Enhanced adsorption-photodegradation of tetracycline using Ce-N-co-doped AC/TiO photocatalyst: isotherms, kinetics, mechanism, and thermodynamic insight.

Excessive use of tetracycline (TC) is alarming owing to its increased detection in water systems. In this study, a photocatalyst was developed to degrade TC using a Ce-N-co-doped AC/TiO photocatalyst, denoted as Ce/N-AC/TiO, prepared using the sol-gel method assisted by microwave radiation, speeding up the synthesis process. Ce/N-AC/TiO achieved maximum TC degradation of 93.
