Decreasing anthropogenic CO2 emissions is compulsory to mitigate the problematic effects of global warming. In that sense, shifting the paradigm from a linear carbon economy to a circular one is a good step in this direction. 1 The Sabatier and the Reverse Water Gas Shift reactions are paradigmatic examples of this strategy. 2 Nonetheless, they imply the need for a catalyst due to the stability of the CO2 molecule. Being so, magnetic induction heating or "magnetically-assisted catalysis" is an already proven feasible technique that helps achieve the required temperature at the active centres using an external magnetic field. This avoids undesired secondary reactions and increases the efficiency of the process while heating and cooling velocity are drastically improved. 3 Under this context, the chemical storage of energy from renewable intermittent sources would be facilitated. In this work, nickel and cobalt ferrites have been synthesized and studied as bifunctional materials. They combine a catalytic activity for CO2 reduction to CO and CH4 and the necessary heating ability for magnetically-assisted catalysis.
