Photocatalytic degradation of tetracycline antibiotic using new calcite/titania nanocomposites

[Display omitted] •A new Calcite/TiO2 nanocomposite was prepared.•Tetracycline antibiotic was degraded using photocatalytic process.•The CAL 30 catalyst is as efficient as pure TiO2.•The configuration of CAL30 can help to save 70% of active catalyst.•The mineralization of Tetracycline takes place mo...
