A combustion synthesis route for magnetically separable graphene oxide–CuFe₂O₄–ZnO nanocomposites with enhanced solar light-mediated photocatalytic activity

Abstract

A novel GO–CuFe2O4–ZnO ternary nanocomposite has been designed as an efficient photocatalyst for the degradation of four toxic organic pollutants.

Enhanced photodegradation of methylene blue with alkaline and transition‐metal ferrite nanophotocatalysts under direct sun light irradiation

“…All the XRD peaks are well indexed to MgFO, CaFO, BaFO, CuFO, and ZnFO according to JCPDS nos. 73‐1720, 32‐0168, 96‐100‐8842, 25‐0283, and 01‐1108, respectively …”

Crumpled sheet like graphene based WO3-Fe2O3 nanocomposites for enhanced charge transfer and solar photocatalysts for environmental remediation

“…Use of graphene/BiVO 4 /TiO 2 nanocomposite, Ag/RGO/ZnO, Ag-Cu 2 O/rGO and graphene oxide-CuFe 2 O 4 -ZnO nanocomposites as photocatalysts for environmental remediation have been reported [30][31][32][33]. In specific, reduced graphene oxide (rGO) based ternary nanocomposites have great superiority than binary composites when used as photocatalysts.…”

Solution Combustion Synthesis of Complex Oxide Semiconductors

“…In general, the oxides derived from SCS have a higher surface area than counterparts synthesized from ceramic, solid-state reaction (SSR) routes; and this factor is reflected in the much higher photoactivity of the SCS oxides. Thus the photodegradation of MB using SCS-CuFe 2 O 4 reached almost 100% in 30 min while only 25.9% was degraded using SSR sample in the similar conditions [23]. This can be rationalized on the small particle size (SCS: 100 nm, SSR: 1-3 μm), and consequently, higher surface area of the SCS sample (SCS: 79.3 m 2 /g, SSR: 2.2 m 2 /g).…”
