One way to mitigate high feedstock cost is to maximize conversion into the bioproduct of interest. This maximization, though, is limited because of the production of CO 2 during the conversion of sugar into acetyl-CoA in traditional fermentation processes. Acetogens are anaerobic bacteria, which cannot grow in oxygenated environments.
A competing reaction, called the hydrogen evolution reaction (HER) or “water splitting,” takes precedence over the CO 2 conversion reaction. One reason is that it performs HER very well, and brings down the CO2 reduction selectivity dramatically. —Haotian Wang, a Rowland Fellow at Harvard University and the corresponding author.

However, most catalysts developed to date for this purpose have the disadvantage of containing metals that are expensive, not widely available and potentially detrimental to the environment. Silyl formate can be easily converted to formic acid, which can serve as an important hydrogen carrier, for example, in fuel cells.
What we know is that this unique structure provides a beneficial chemical environment for CO2conversion to multicarbon products,” he said. Exactly how that is happening is still unclear, said Yang, who is also a professor at UC Berkeley’s Department of Materials Science and Engineering.
Our group has found that you can do various tricks with the local environment of the catalyst to provide that selectivity.

Additionally, because it is inorganic, silver remains more stable under harsh catalytic environments. Testing under identical conditions confirmed the non-porous silver catalyst’s significant advantages over other silver catalysts in water environments.
When we began this study, we wondered, maybe the key to a better solar fuels device isn’t in the material by itself but in the overall environment of the reaction, including the electrolye. We knew it was unstable—but we were surprised to learn just how unstable it really is. —Francesca Toma.
