Fenton-mediated thermocatalytic conversion of CO₂ to acetic acid by industrial waste-derived magnetite nanoparticles

Abstract

Steel industry waste-derived rod-like Fe3O4-NPs were used for thermo-catalytic reduction of CO2 to acetic acid in aqueous-H2O2 medium. H2O2 facilitates the reaction by generating high concentrations of OH˙ and H+/˙, supporting high acetic acid yield.

Multiphase Reduced Iron Oxide Nanoparticles for Hydrogenation of Mono-, Di-, and Tri-Nitrophenols

“…Most of these work used expensive metals like Ag, Au, and Pt to reduce nitrophenols therefore, a cost-effective catalyst for reducing toxic nitrophenols is needed. For the same, Fe-oxide-based catalysts have widely been in use for the reduction of nitroaromatics in the presence of reducing agents like hydrazine hydrate (NH 2 NH 2 ·H 2 O) and sodium borohydride (NaBH 4 ). − Moreover, to achieve more sustainability, as an alternative, inert iron oxide dust (IOD) in the form of α-Fe 2 O 3 (available low cost as a waste byproduct from steel industries) can used as a starting material for the synthesis of some Fe-based catalysis. − …”
