Recent advances in ambient electrochemical methane conversion to oxygenates using metal oxide electrocatalysts

“…Gas-tight rotating cylindrical electrodes can be rotated or pressurized, as a consequence of which the activity can be changed. 56,57,122,123 For a The proportion of CH 3 OH containing 18 O and 16 O was calculated and found to be 38% and 62%, respectively. Typical MS for CH 3 OH (bottom panel).…”

Isotopic Oxygen Exchange Study to Unravel Noble Metal Oxide/Support Interactions: The Case of RuO2 and IrO2 Nanoparticles Supported on CeO2, TiO2 and YSZ

“…[1,2] For instance, noble metal or noble metal oxide-based catalysts interfaced with active supports are increasingly used in catalytic oxidation reactions, [1,3] low temperature solid oxide fuel cells (SOFC) [4][5][6] and electrochemical promotion of catalysis. [7][8][9][10][11][12] The oxygen mobility property is of paramount importance, especially when oxygen from the gas phase is scarce or not stable in concentration. [3] As new synthesis methods emerge and result in highly active catalysts, further characterization is required to understand the role of lattice oxygen from the support to attempt in explaining the enhanced catalytic rate.…”

Demystifying the Atomistic Origin of the Electric Field Effect on Methane Oxidation

“…Since the discovery of EPOC in the early 1980s, over 100 different catalytic reactions have been performed displaying the EPOC effect for various reactions and reactor types. − A detailed atomistic understanding of the influence of the electric potential on the surface state and the corresponding catalytic properties is still an active topic of research. − Such insight is a crucial factor in interpreting the experimental observations and putting conclusions from past studies on solid theoretical ground. An elucidation on what is occurring during the reaction could allow for the development of an efficient and novel catalytic electrode design that can fully exploit the power of EPOC, i.e., operate at rather low temperature and still display superior catalytic activity for key reactions such as the complete oxidation of methane, , NO x reduction, complete oxidation of volatile organic compounds (VOCs), − and CO 2 hydrogenation. − …”
