Special Issue Information

Dear Colleagues,

The Special Issue is dedicated to the exploration of catalytic reforming and hydrogen production, delving into a journey starting in the past of these processes and ending in their future applications. The catalytic reforming of light hydrocarbons stands out as a prominent technique for generating valuable products like synthesis gas. Syngas, a crucial intermediary substance in the creation of hydrogen, ammonia, methanol, and synthetic hydrocarbon fuels, holds significant potential for fostering a cleaner, more sustainable energy environment. Furthermore, through advancements in catalyst development, reactor designs, and process optimization strategies, hydrogen has emerged as a pivotal player in the global energy shift towards a more efficient and sustainable hydrogen economy.

This Special Issue aims to showcase the most recent research findings in heterogeneous catalysis concerning catalytic reforming and hydrogen production, assuming a future where clean energy takes center stage. We invite submissions in the form of original research papers or reviews that reflect the state of the art of this research area. Topics of interest include, but are not limited to, the following:

  • Methane conversion.
  • Dry reforming.
  • CO2 methanation.
  • Hydrogen production processes.
  • Water–gas shift (WGS) reaction.
  • Production of syngas.
  • Fischer–Tropsch synthesis.
  • Fuel cells.

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 submissions that pass pre-check are 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 2700 CHF (Swiss Francs).

To investigate the influence of Ag and the loading of Ni species, Ni-Ag type catalysts were synthesized with varying Ni/Ag ratios (1, 1.5 and 2) using the coprecipitation method. The catalysts were extensively characterized using various techniques such as TG-DSC-SM, XRD, ICP, BET, SEM-EDX and TPR and subsequently tested in the CH4/CO2 reaction without any pretreatment. Regardless of the ratio employed, a phase mixture containing NiO and Ag was observed after calcination under air between 600 °C and 1200 °C. SEM analysis confirmed the presence of a close interface between Ag and NiO. The specific surface area was found to be significantly higher for the catalyst with lower Ni content (R = 1). TPR analysis demonstrated that the inclusion of Ag facilitated the reduction of Ni at lower temperatures. XRD analyses of the spent catalyst confirmed catalyst reduction during the reaction. Among the samples, a catalyst with Ni/Ag = 1 exhibited superior catalytic activity without any pretreatment under a reduction atmosphere, in which case the conversions of methane and CO2 at 650 °C amounted to 38 and 45 mol%, respectively, with H2/CO = 0.7 and 71 mol% of H2. The presence of Ag species enhances the stability of the Ni catalyst and improves catalytic performance in the dry reforming of methane. Full article
