Special Issue Information

Dear Colleagues,

Adsorption processes and heterogeneously catalyzed reactions take place at the surface of materials. Because of the low radiation energy involved, vibrational spectroscopies remain indispensable techniques providing unique information on key surface properties, including the molecular structure of active sites and the nature of acid and basic sites. This Special Issue on “In situ and operando vibrational spectroscopy” will provide updates on the recent advances in our understanding of catalytic and adsorption processes, taking place at the gas–solid and liquid-phase interfaces, using vibrational spectroscopy. Topics related to in situ characterization, operando characterization, elucidation of reaction mechanisms, adsorption, time-resolved experiments, modulation-type experiments, and isotope exchange will be of interest. Contributions to this Special Issue are expected to include structural analysis and properties assessment of active sites in catalysts and sorbents. Characterization of surface species during reaction would be just ideal. Submissions to this Special Issue are welcome in the form of original research papers or short reviews reflecting knowledge in the field of characterization of materials within the following thematic subjects: catalytic processes; adsorption for capture/storage/separation applications; processes on minerals and soils; electrocatalysis; and structure by in situ/operando spectroscopy.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Catalysts is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Title: Operando Infrared Spectroscopic study on CO2 Methanation Catalysts
Author: Per-Anders Carlsson

Title: Operando Investigation of the Toluene Combustion on Palladium-Gold supported on ceria catalysts
Authors: Aline Villarreal, Sebastian Collins
Abstract: Toluene total oxidation on monometallic Au/CeO2 and Pd/CeO2, and bimetallic PdAu/CeO2, catalysts was investigated by an operando DRIFT-MS. These catalytic systems were characterized by transmission electron microscopy, CO adsorption by FTIR and UV-Vis spectroscopy. An optimized plug-flow DRIFT cell was employed in order to obtain quantitative kinetic information of the surface concentration of surface intermediates. The results of catalytic activity indicate that there is a synergy between both metals, showing a higher activity in the bimetallic system (Pd-Au/CeO2). Operando Modulation Excitation DRIFT Spectroscopy (MES) was employed to investigate the reaction mechanism. Benzaldehyde and carbenium ion were indentified as key reaction intermediates.
