Abstract
The present, disclosure relates generally to reactor cells comprising an enclosure and one or more plasmonic photocatalysts on a catalyst support disposed within the enclosure. In some embodiments of the disclosure, the enclosure is at least partially optically transparent.
Claims27
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.

A reactor cell comprising:
- an enclosure comprising at least one input, at least one output, and a central cavity;
- a light source disposed in the central cavity;
- and
- at least a first plasmonic photocatalyst and a second plasmonic photocatalyst on a catalyst support disposed within the enclosure and substantially surrounding the central cavity, wherein each of the at least the first plasmonic photocatalyst and the second plasmonic photocatalyst comprises a respective catalyst coupled to a plasmonic material having a plasmon resonant frequency designed to catalyze a desired chemical reaction by maximizing absorption of at least a predetermined target wavelength in the electromagnetic spectrum, and wherein the second plasmonic photocatalyst differs from the first plasmonic photocatalyst and maximizes absorption of at least a different predetermined target wavelength from that of the first plasmonic photocatalyst.

A method for transforming at least one reactant gas, the method comprising:
- supplying at least one reactant input gas via at least one delivery channel into a reactor cell that comprises at least a first plasmonic photocatalyst and a second plasmonic photocatalyst on a catalyst support packed as a fixed bed substantially filling an enclosure, 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, and 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;
- illuminating, via at least one light source, substantially an entirety of at least an interior of the enclosure while the at least one reactant input gas is passed through the enclosure;
- and
- outputting at least one output gas from the reactor cell,
- wherein, upon illuminating substantially the entirety of at least the 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.
