Abstract: Disclosed is a process for converting methane into value-added compounds. In this process, a gas mixture containing hydrogen as well as high-concentration acetylene formed through methane pyrolysis (e.g. non-oxidative coupling of methane) is selectively hydrogenated in the presence of a bimetallic supported catalyst. This process obtains ethylene from acetylene in the gas mixture while unreacted methane and hydrogen are recovered as byproducts and/or additionally recycled.

Abstract: An electrochemical hybrid catalyst has a structure in which a nitrogen-doped carbon nanostructure (N—C) composite is loaded or decorated with two single atom transition metals indirectly linked adjacent to each other, and thus exhibits high carbon monoxide selectivity and current density at a low overpotential during reduction reaction for converting carbon dioxide into carbon monoxide, and a carbon dioxide conversion system uses the same.
