Abstract Titanium dioxide (TiO2) has a strong oxidation effect when absorbing ultraviolet light. Therefore, when TiO2 is used as a light stabilizer in polyvinyl chloride (PVC), it will cause the photodegradation of PVC. Herein, carbon quantum dots (CQDs) coated TiO2 composite (TiO2@CQDs) was prepared by a one-step hydrothermal method.
