摘要
Although steady progress has been achieved toward upcycling waste CO2 through diverse catalytic strategies, each approach has distinct limitations, hampering the generation of complex products like sugars. Here, we provide a roadmap that evaluates the feasibility associated with state-of-the-art electrochemical processes eligible for converting CO2 into glycolaldehydes and formaldehydes, both essential components for sugar generation through the formose reaction. We establish that even in low concentrations, glycolaldehyde plays a crucial role as an autocatalytic initiator during sugar formation and identify formaldehyde production as a bottleneck. Our study demonstrates the chemical resilience of the formose reaction successfully carried out in the chemically complex CO2 electrolysis product stream. This work reveals that CO2-initiated sugars constitute an adequate feedstock for fast-growing and genetically modifiable Escherichia coli. Altogether, we introduce a roadmap, supported by experimental evidence, that pushes the boundaries of product complexity achievable from CO2 electroconversion while integrating CO2 into life-sustaining sugars.
