1. A fixed-bed reactor cell comprising:
an optically transparent cylindrical enclosure;
a first fitting to attach the reactor cell at a first end of the enclosure to at least one delivery channel for receiving at least one reactant input gas;
a second fitting to attach the reactor cell at a second end of the enclosure to at least one delivery channel for outputting at least one output gas;
a catalyst support packed as a fixed bed substantially filling the enclosure;
a first plasmonic photocatalyst supported by the catalyst support, wherein the first plasmonic photocatalyst comprises a catalyst coupled to a plasmonic material having a first plasmon resonant frequency designed to catalyze a desired chemical reaction by maximizing absorption of at least a first predetermined target wavelength in the electromagnetic spectrum;
a second plasmonic photocatalyst supported by the catalyst support, wherein the second plasmonic photocatalyst differs from the first plasmonic photocatalyst and maximizes absorption of at least a second predetermined target wavelength in the electromagnetic spectrum,
wherein, upon application of a light source to substantially an entirety of at least an interior of the enclosure while the at least one reactant input gas is passed through the enclosure, the reactor cell is configured to transform the at least one reactant input gas into the at least one output gas via the at least one reactant input gas reacting with at least the first plasmonic photocatalyst or the second plasmonic photocatalyst.
