Albeit a variety of available strategies for CO 2 conversion to useful chemicals and fuels, most technologies require relatively pure CO 2 , especially without oxygen and water.This requires additional steps of CO 2 capture and purification before its efficient conversion. This necessity increases energy requirement, leading to poorer carbon footprints and higher capital expenditures lowering the viability of overall CO 2 conversion processes. We have developed an effective technology which combines CO 2 capture and conversion processes using isothermal unsteady-state operation and a catalyst consisting of earth-abundant chemical elements (FeCrCu/K/MgO-Al 2 O 3 ).Diluted CO 2 streams common in process flue gases, even containing oxygen and water, can be fed to the process and relatively pure product stream such as syngas, i.e. carbon oxides (CO and CO 2 ) and hydrogen mixture, can be produced. A possible scheme of reactor integration for continuous CO 2 abatement and conversion based on a tworeactors system is presented.

The binder free Sn-GDE obtained by electrodeposition allows CO2 electroreduction to formate with low energy consumption for sustainable fuel production.
