Recyclable CoFe2O4–Ag2O magnetic photocatalyst and its visible light-driven photocatalytic performance

Recyclable CoFe2O4–Ag2O magnetic photocatalyst and its visible light-driven photocatalytic... A magnetically separable photocatalyst, the composite compound CoFe2O4–Ag2O, was fabricated successfully by a simple precipitation method and used for photodegradation of organic pollutants under visible light (>420 nm) irradiation. Its magnetic separation performance was evaluated.

As prepared, CoFe2O4–Ag2O (60%) has a coercivity of 2500 Oe and a saturation magnetization of 22.45 emu g−1; it can be completely separated magnetically in 20 s with magnetic recovery mass rate of 85% under an external magnetic field. This superb photocatalytic performance and separation recovery confirms that the CoFe2O4–Ag2O photocatalyst is a promising candidate for future use in photo-oxidative degradation of organic contaminants. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

A magnetically separable photocatalyst, the composite compound CoFe2O4–Ag2O, was fabricated successfully by a simple precipitation method and used for photodegradation of organic pollutants under visible light (>420 nm) irradiation. Its magnetic separation performance was evaluated. Results showed that the CoFe2O4–Ag2O with 60-wt% content of Ag2O had the best photocatalytic performance, stability, and magnetic separation performance. Methyl orange, methylene blue, rhodamine B, and phenol can be completely photodegraded by the CoFe2O4–Ag2O photocatalyst in a short period. After five cycles, CoFe2O4–Ag2O kept its performance stability. As prepared, CoFe2O4–Ag2O (60%) has a coercivity of 2500 Oe and a saturation magnetization of 22.45 emu g−1; it can be completely separated magnetically in 20 s with magnetic recovery mass rate of 85% under an external magnetic field. This superb photocatalytic performance and separation recovery confirms that the CoFe2O4–Ag2O photocatalyst is a promising candidate for future use in photo-oxidative degradation of organic contaminants.
