This article proposes a model that accounts for the modes in which aqueous gas depletion evolves over time and affects the long-term CO 2 electroreduction and the corresponding pH evolution near the electrode’s surface. Therefore, the extent to which H 2 is produced can be used as a metric to evaluate the efficiency of CO 2 RR.

During CO 2 hydrogenation, CO 2 is initially reduced to CO by hydrogen via the reverse water-gas shift (RWGS) on Fe 3 O 4 sites, followed by a subsequent hydrogenation of CO to α-olefins via Fischer–Tropsch synthesis (FTS) on Fe 5 C 2 sites.

Researchers at Nanjing University and Anhui Polytechnic University in China have synthesized zinc orthogermanate (Zn 2 GeO 4 ) ultralong nanoribbons which show promising photocatalytic activity toward the reduction of CO 2 into renewable methane (CH 4 ) and water.

The lab produced a brown, spongy material in which hydrophobic (water-avoiding) buckyballs forced the hydrophilic (water-seeking) amines to the outside, where passing carbon dioxide could bind to the exposed nitrogen. The Rice lab used buckyballs as crosslinkers between amines, nitrogen-based molecules drawn from polyethyleneimine.

The direct fuel cell produces electricity, with water and CO 2 as byproducts of the oxidation of the liquid fuel in the fuel cell. Although there are “ open issues ” with longevity, the SOEC devices have “ good performance ” in splitting water, the authors note. Energy Fuels , Article ASAP doi: 10.1021/ef900111f.

To avoid CO 2 emissions associated with H2-production, electrolysis of water powered by solar, wind or hydroelectricity would be a preferred source and has achieved a level of maturity and success. Alternatively, syngas can be added to sugar fermentation to provide the necessary reducing power and carbon. … Antoniewicz, Eleftherios T.
