Abstract
- [Display omitted] • A new highly efficient and magnetic photocatalyst was proposed. • The synthetic method developed was very simple. • It had good photocatalytic ability for MB under simulated sunlight. • The presented photocatalyst was recyclable. Herein, Fe 3 O 4 @Ru-doped TiO 2 photocatalyst was developed successfully by a facile chemical strategy. The sample with 0.2% doping Ru showed the best photocatalytic activity, which could photodegrade 70.20% of methylene blue after 120 min of simulated sunlight exposure, and kept good degradation efficiency and recovery after 5 cycles. It could be attributed that the Ru-doping alleviated the band gap energy to make the electron-hole pairs easier to generate and enhanced the synergistic effect to increase the carrier separation efficiency. The present work provided a development prospect of simple preparation of recoverable photodegradation catalyst for environmental organic pollutants. [ABSTRACT FROM AUTHOR]
