Facile Synthesis of Visible Light-Induced g-C<sub>3</sub>N<sub>4</sub>/Rectorite Composite for Efficient Photodegradation of Ciprofloxacin

Facile Synthesis of Visible Light-Induced g-C<sub>3</sub>N<sub>4</sub>/Rectorite Composite for Efficient Photodegradation of Ciprofloxacin

A novel kind of g-C<sub>3</sub>N<sub>4</sub>/rectorite composite with high visible-light photoactivity was developed via a mild and cost effective two-step process. Ciprofloxacin (CIP), a typical antibiotic, was applied to evaluate the photoactivity of the received catalysts....
