Iron oxide dust, discarded as industrial waste, has been used here to fabricate magnetic iron oxide nanoparticles (Fe 3 O 4 -NPs). We have proposed the thermo-catalytic reduction of carbon dioxide (CO 2 ) using Fe 3 O 4 -NPs in the presence of H 2 O 2 to get acetic acid (AcOH) at near ambient conditions (100 °C, 10 bar) with a maximum yield of ∼0.4 M in a batch-reactor. The importance of H 2 O 2 can be described as it facilitates the production of higher concentrations of OH˙ and H +/ ˙, which consequently supports the synthesis of AcOH.
