NOVELTY - The process for producing hydrogen involves: (a) adding a feed gas to an electromagnetic embedding enclosure (E/MEE); (b) exposing the feed gas to at least one E/MEE light source; (c) directing the feed gas to a reactor assembly, where the reactor assembly has a gas inlet and gas outlets, a reactor chamber containing a nanoporous carbon disposed within a cup and, optionally, covered with a cap, a first porous frit defining a floor of the reactor chamber disposed within the cup, a second porous frit defining the ceiling of the reactor chamber, a reactor head space disposed above the reactor chamber, and at least one reactor assembly coil surrounding the reactor chamber and/or reactor head space operably connected to a power supply; (d) subjecting the nanoporous carbon to harmonic patterning to instantiate hydrogen; (e) collecting a product gas comprising the hydrogen; and (f) isolating the hydrogen from the product gas. USE - Process for producing hydrogen. ADVANTAGE - The recycling or reusing the carbon can enhance metal nanostructure yields and adjust nucleation characteristics enabling change in element selectivity and resultant distributions. DETAILED DESCRIPTION - The process for producing hydrogen involves: (a) adding a feed gas to an electromagnetic embedding enclosure (E/MEE); (b) exposing the feed gas to at least one E/MEE light source; (c) directing the feed gas to a reactor assembly, where the reactor assembly has a gas inlet and gas outlets, a reactor chamber containing a nanoporous carbon disposed within a cup and, optionally, covered with a cap, a first porous frit defining a floor of the reactor chamber disposed within the cup, a second porous frit defining the ceiling of the reactor chamber, where each porous frit has a porosity that is sufficient to allow a gas to permeate into the reactor chamber, a reactor head space disposed above the reactor chamber, and at least one reactor assembly coil surrounding the reactor chamber and/or reactor head space operably connected to a power supply, where a computer processing unit is configured to control the power supply to the reactor assembly coil; (d) subjecting the nanoporous carbon to harmonic patterning to instantiate hydrogen; (e) collecting a product gas comprising the hydrogen; and (f) isolating the hydrogen from the product gas. An INDEPENDENT CLAIM is included for the product gas.
