Study On Novel Fe3O4@UiO-66@Bi2O3 Synthesis for Effective Methyl Orange Photocatalytic Degradation

Abstract With the booming industry, the demand for dyes has increased dramatically and the discharge of wastewater containing dyes has also increased dramatically. Owing to the multi-pore nature and stabilization of UiO-66, the relatively small band gap of Bi 2 O 3 and the good magnetic properties of Fe 3 O 4 , Fe 3 O 4 @UiO-66@Bi 2 O 3 has good efficiency and reusability to remove methyl orange (MO). The maximum degradation rate is 83.26%, and the magnetic properties of Fe 3 O 4 solved the problem of difficult recovery of UiO-66 as a nanomaterial with a recovery rate of 98.79%. In this work, the results showed that the Fe 3 O 4 @UiO-66@Bi 2 O 3 catalysts composite increased the specific surface area, improved the separating efficiency of both holes and electrons as well as significantly enhanced the photo-catalytic efficiency in comparison to single Fe 3 O 4 @UiO-66 and Bi 2 O 3 @UiO-66 materials. The photocatalytic decomposition procedure is consistent with the primary reaction kinetics. The outcomes suggest that Fe 3 O 4 @UiO-66@Bi 2 O 3 (FUB) is a strong contender for the removal of MO.
