Photo-electrocatalytic degradation of tylosin by TiO2 nanotube modified photoelectrode: Synthesis, kinetics, and mechanism investigations

•A new solid Ag/g-C3N4/TiO2 NTs catalyst was successfully prepared, which effectively improved the recovery performance of the catalyst.•Thanks to the construction of heterojunctions and the conductive bridge of metal nanoparticles, carrier recombination is inhibited, which greatly enhances the degradation performance of the catalyst.•The degradation process of TYL is mainly through the cleavage of CC, CN and CO bonds.•The ECOSAR software evaluation showed that TYL and its intermediates gradually decreased or even nontoxic after degradation.
