Interests: high-resolution analytical electron microscopy in catalysis; structure-activity correlations in pure and complex oxide catalysts; interfacial engineering of the metal-oxide phase boundary; reactive activation of intermetallic compounds in catalysis; mechanism of methanol and methane steam reforming reactions; preparation and characterization of complex oxide, bi- and multimetallic thin film catalyst systems; operando and in situ structural and spectroscopic studies of catalysts
Steam reforming of hydrocarbons (mostly methane) or alcohols (mostly methanol and ethanol) is one of the most promising and effective routes to enhanced hydrogen production. The most crucial step of this reaction is the efficient water activation, which is a necessary prerequisite for both a high CO2 selectivity and an associated high hydrogen yield. The reactions have been studied on a variety of different catalytic surfaces encompassing oxides, supported metal-oxide systems or (supported) intermetallic compounds likewise. The controllable steering of product selectivity is thereby an obvious key criterion for technical usage. For methanol steam reforming, the key targets—apart from pronounced CO2 selectivity—are, thus, a maximum hydrogen yield and a low CO content in the reformate to realize the efficient on-board production of clean hydrogen in, e.g., automotive applications. Given the structural and chemical complexity and diversity of the materials used, the question about the common elementary reaction steps of the steam reforming reaction is imperative. For structurally complexer materials, such as the recently-put-forward oxide-supported Pd-based intermetallic phases, a bifunctional synergism is usually assumed, where the participating catalytic entities (or the in situ created interface) synergistically act in the catalytic reaction.
This particular Special Issue of Catalysts is, therefore, aimed at providing details and showing promising state-of-the-art research on latest developments in unraveling the mechanisms of the steam reforming reaction on a variety of different catalytic material classes, including oxides, metal-oxide systems and intermetallic compounds.

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 1000 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.
