CO2 and H2O conversion to solar fuels via two-step solar thermochemical looping using iron oxide redox pair

Highly efficient water splitting and carbon dioxide reduction into formic acid with iron and copper powder

“…There have been a large amount of methods for the CO 2 reduction proposed [1][2][3][4][5][6][7][8][9][10][11]. Among these methods, the photochemical reduction of CO 2 is regarded as the most potential process, however, its efficiency is very low [1].…”

A review on solar thermal syngas production via redox pair-based water/carbon dioxide splitting thermochemical cycles

“…The research group of PROMES studied co-splitting of H 2 O and CO 2 over FeO (produced via solar thermal reduction of Fe 3 O 4 ) in a TGA configuration. They also reported that H 2 production was favored over CO production with the WS reaction being responsible for over 80% of the global FeO conversion [112]. In a recent work by the group of Aerosol and Particle Technology Laboratory (APTL), of CERTH, Thessaloniki, Greece, Ni-ferrite was shown to successfully simultaneously split CO 2 and H 2 O under a co-feeding mode of operation to CO and H 2 with a H 2 /CO ratio close to 1.40.…”

Materials-Related Aspects of Thermochemical Water and Carbon Dioxide Splitting: A Review

“…The production of fuel through the intermediate production of synthesis gas is discussed in the literature, as well [29,30,31,32,33]. …”
