Abstract

Abstract Resistive heating of the metal surface of a supersonic molecular beam nozzle is shown to be very effective in converting CO2 diluted in H2 to CO and H2O via the reverse water–gas shift (RWGS) reaction at temperatures that preclude simple pyrolysis. The conversion of CO2 to CO, referred to herein as “RWGS yield,” exceeds 80% at nozzle temperature above 1000 K, with a detectable methane byproduct. The stainless-steel surface of the nozzle appears to facilitate the reaction as a heterogeneous catalyst. Reaction yield is observed to increase with nozzle temperature and, when the gas mixture contains a significant excess of H2, decrease with increasing in nozzle stagnation pressure. The inverse dependence of the reaction on stagnation pressure is used to propose a reaction mechanism. Additional kinetic control over the mechanism is afforded by adjusting reactant partial pressures and residence times inside the nozzle reactor, highlighting this method’s utility in screening heterogeneous catalysis reactions with fine control over mass flow rates, pressure, and temperature. The results of this study, therefore, present a route to efficient, high pressure, inline catalysis as well as a method to rapidly assess the viability of new catalysts in development.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
