Artificial photosynthesis systems are proposed as an efficient alternative route to capture CO2 to produce additional food for growing global demand. Here a two-step CO2 electrolyser system was developed to produce a highly concentrated acetate stream with a 57% carbon selectivity (CO2 to acetate), allowing its direct use for the heterotrophic cultivation of yeast, mushroom-producing fungus and a photosynthetic green alga, in the dark without inputs from biological photosynthesis. An evaluation…

Cell-free chemoenzymatic starch synthesis from carbon dioxide

The artificial starch anabolic pathway (ASAP), consisting of 11 core reactions, was drafted by computational pathway design, established through modular assembly and substitution, and optimized by protein engineering of three bottleneck-associated enzymes.

CO2 electrolysis to multicarbon products at activities greater than 1 A cm−2

A catalyst:ionomer bulk heterojunction (CIBH) architecture that decouples gas, ion, and electron transport and achieves CO2 electroreduction on copper in 7 M potassium hydroxide electrolyte with an ethylene partial current density at 45% cathodic energy efficiency.
