Synergistic cobalt oxide/reduced graphene oxide/biochar nano-composite catalyst: harnessing the power of the catalyst for sustainable remediation of organic dyes and chromium(vi)

Abstract

The first-ever report on the use of a Co3O4/reduced graphene oxide/biochar composite as an inexpensive, easily separable, and highly reactive visible light active photocatalyst.

Shining Light on Environmental Remediation: A type-II heterojunction MnFe2O4/rGO Nanocomposites for Enhanced Photocatalytic Degradation of organic dyes and Bisphenol A

“…The morphology of the MF/rGO-10 composite, however, demonstrates a combination of MnFe2O4 particles and a slight amorphous character of rGO, indicative of successful composite formation. The observed aggregation of MnFe2O4 nanoparticles suggests potential van der Waals attraction or dipolar interactions between particles(Pathania et al, 2015;Priyadarsini et al, 2024). EDAX analysis further confirmed the precise composition of all components, Fe, Mn, and O, in the synthesized heterostructure.…”

“…Graphene oxide (GO) was synthesized via a sequence of carefully regulated steps (Priyadarsini et al, 2024) .The procedure started by taking 46 ml of a mixture of 1 g of concentrated graphite flakes and 1 g of NaNO3 together with concentrated H2SO4 in an ice bath. After swirling the mixture for 15 min, 8 g of KMnO4 was added gradually.…”
