A novel electrochemical cell for operando X-ray absorption measurements at low energies: Probing electrochemically induced electronic changes in palladium
(2018-09-01)
Operando assessment of electronic properties near the Fermi level is essential to gain new insights into the mechanisms of electrochemical reactions as well as for the development of more efficient electrocatalysts. However, ...
Identification of key reaction intermediates during toluene combustion on a Pd/CeO2 catalyst using operando modulated DRIFT spectroscopy
(Elsevier Science, 2021-09)
Operando DRIFT spectroscopy is used to elucidate the role of key reaction intermediates during toluene oxidation on a Pd/CeO2 catalyst and bare CeO2 support. Selective identification of active surface species and their ...
DRIFT+MS Quantitative Study of the CO Oxidation on Gold supported on Ceria
(VI San Luis School and Conference on Surfaces, Interfaces and Catalysis, 2019)
The steps of the CO oxidation reaction on a Au/CeO2 catalyst was quantitatively investigated using a novel DRIFT cell/micro-reactor. The design and characterization of this DRIFT cell/micro-reactor, coupled with mass ...

Operando tracking of oxidation-state changes by coupling electrochemistry with time-resolved X-ray absorption spectroscopy demonstrated for water oxidation by a cobalt-based catalysts film
(2021)
Transition metal oxides are promising electrocatalysts for water oxidation, i.e., the oxygen evolution reaction (OER), which is
critical in electrochemical production of non-fossil fuels. The involvement of oxidation state ...
Operando DRIFTS and DFT Study of Propane Dehydrogenation over Solid- and Liquid-Supported GaxPty Catalysts
(American Chemical Society, 2019-04)
Supported catalytically active liquid metal solutions (SCALMS) represent a class of catalytic materials that have only recently been developed, but have already proven to be highly active, e.g., for dehydrogenation reactions. ...
Total methanol oxidation studied by MS-DRIFT operando and MES on bimetallic Au-Pd catalysts
(American Chemical Society, 2019)
The mechanism of methanol oxidation was investigated by combining operando and modulation-excitation diffuse reflectance infrared spectroscopy (MES-DRIFT) over monometallic Au/CeO2-ZrO2(CZ) and Pd/CZ catalysts, and also ...
