Capture or convert?
It doesn't have to capture at all, just convert the CO2 into something useful elsewhere or at least less harmful.
ex: in auto catalytic converters pollutants are combined with atmospheric oxygen to make other compounds without sequestration.
The goal of the synthetic photosynthesis researchers is conversion of CO2 into compounds that can be converted into alcohol, presumably for use as a fuel source.
CO2 in, E100 out.
Converters of this type need very little of the actual catalyst, just enough to very thinly coat the active surface of the supporting matrix.
