Within the realm of renewable energy, CO 2-based e-fuels have emerged as a promising technology that attempts to convert atmospheric CO 2 into clean fuels. The process involves production of synthetic gas or syngas (a mixture of hydrogen and carbon monoxide (CO)). With the help of the reverse water-gas shift (RWGS) reaction, CO
