Synthesis, characterization and application of magnetic carbon materials as electron shuttles for the biological and chemical reduction of the azo dye Acid Orange 10

A set of core(ferrite, FeO)-shell(carbon, C) composites, [email protected], [email protected], [email protected], and carbon nanotubes (CNT) impregnated with 2% of Fe ([email protected]%Fe) were prepared. The different composites were tested as redox mediators (RM) in the biological reduction of the azo dye Acid Orange 10 (AO10). Materials were tested at different concentrations from 0.1 to 1.0 g L−1. In the absence of RM, the AO10...
