Abstract
Nanofibers-based materials are among the promising photocatalysts for degrading organic pollutants. In this work, CeO2/Co3O4 nanofibers, which absorb a wide spectrum of visible light, were prepared by electrospinning technique. Then, the quaternary CeO2/Co3O4/Ag/Ag3PO4 step-scheme composites were synthesized by precipitation route. Various characterizations like FE-SEM, EDS, DRS, XRD, XPS, PL and FT-IR were conducted to determine the morphology, structure and properties of samples. The photocatalytic efficiency of as-prepared composites were investigated by the degradation of MB under blue LED light irradiation. Quaternary CeO2/Co3O4/Ag/Ag3PO4 composites exhibit higher photocatalytic performance than CeO2 and CeO2/Co3O4. Particularly, this composite yielded 92.5% degradation of MB in 80 min, and the degradation rate of MB by the photocatalyst was almost 0.03 min−1, which was 4.8 times faster than that over CeO2/Co3O4 NFs. The significant increase in the reaction rate of MB photo-degradation can be related to SPR effect, the inhibition of charge–carrier recombination and formation S-scheme system.
