Fenton-mediated thermocatalytic conversion of CO2 to acetic acid by industrial waste-derived magnetite nanoparticles† Iron oxide dust, discarded as industrial waste, has been used here to fabricate magnetic iron oxide nanoparticles (Fe3O4-NPs). We have proposed the thermo-catalytic reduction of carbon dioxide (CO2) using Fe3O4-NPs in the presence of H2O2 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.

Deploying used solid carbon dioxide to assist graphite exfoliation† Herein, we describe the possibility of using solid CO2, also known as dry ice, as an exfoliating agent for thermal-assisted exfoliation of graphite. Used dry ice has been chosen over supercritical CO2 for its easy availability after storage purposes. HRTEM analysis showed the increased spacing between the stacked graphite layers after exfoliation.
