Deactivation of CO2(010) and CO2(001) by hydrogen and deuterium

The Journal of Chemical Physics, 1976
The probabilities of deactivating the bending and asymmetric stretching modes of CO2 by hydrogen and deuterium are calculated semiclassically over the temperature range of 300–2000 °K. It is assumed that the molecular interaction potential consists of a superposition of atomic pair repulsion forces.

Porous MoxCy/SiO2 Material for CO2 Hydrogenation

Topics in Catalysis, 2019
The synthesis and characterization of an inexpensive porous MoxCy/SiO2 material is presented, which was obtained by mixing ammonium hexamolybdate, sucrose, and a mesoporous silica (SBA-15), with a subsequent heat treatment under inert atmosphere. This porous material presented a specific surface area of 170 m2/g.

Electrochemical reduction of CO2 on hydrogen-enriched and hydrogen-depleted surfaces

Journal of the Chemical Society, Faraday Transactions, 1994
A cell using Pd foil is proposed for investigating the mechanism of electrochemical reduction where surface hydrogen activity is controlled separately from the potential. Hydrogen is supplied to the surface from behind by reverse-face electrolysis (hydrogen-enriched surface) but, without this electrolysis, hydrogen is removed from the surface by ...

Infrared spectra of CO2-doped hydrogen clusters, (H2)N–CO2

The Journal of Chemical Physics, 2012
Clusters of para-H2 and/or ortho-H2 containing a single carbon dioxide molecule are studied by high resolution infrared spectroscopy in the 2300 cm−1 region of the CO2 ν3 fundamental band. The (H2)N–CO2 clusters are formed in a pulsed supersonic jet expansion from a cooled nozzle and probed using a rapid scan tunable diode laser. Simple symmetric rotor

Hydrogenated Detonation Nanodiamond as a Catalyst for CO2 Reduction

Carbon
The ability of hydrogenated detonation nanodiamond particles to participate in CO2 reduction reactions producing formate and acetate ions on their surface was demonstrated. The reactions proceed in air and CO2 under normal conditions and do not require light, thermal and electrochemical activation.

Hydrogenation of CO2 for methanol production

2012
Converting CO2 to valuable products becomes increasingly interesting as CO2 emissions are restricted and penalties have to be paid. Different processes are evaluated and a systematic design is made for the most promising concepts. The goal is to produce 10 kton/yr methanol from a typical flue gas stream containing 12 mole % CO2.

Hydrogen production with CO2 capture

Hydrogen is primarily produced from methane reforming and coal gasification, but these processes generate significant CO₂ emissions. The sorption-enhanced water-gas shift (SE-WGS) reaction is a promising technology that enables in-situ CO₂ capture during methane reforming while enhancing H₂ production through equilibrium shifts.
