Special Issue Information

Dear Colleagues,

Currently, an important issue in chemical processes is the selection of a suitable catalyst that is characterized by high activity and selectivity. These catalytic features have nickel catalysts, which are commonly used for various processes such us syngas production, hydrogen generation, fuel fraction production, hydroconversion of paraffin waxes and others. They are widely used because of their low cost. Typically, their reactivity is strongly dependent on the dispersion of the active phase, the size of the specific surface area, particle size of nickel species and the interaction between nickel species and support. The disadvantage of nickel-supported catalysts is their short life caused by a strong deactivation of the active centers due to coke deposition, oxidation and sintering of the metallic active phase. One possible solution to this problem is the use of a suitable metallic or structural modifiers introduced into the catalytic system.

This Special Issue will present the most recent and significant developments in nickel catalysis and processes, where such systems are widely used. Original papers on the above topics and short reviews are welcome for submission.

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.

Highly-Dispersed Ni-NiO Nanoparticles Anchored on an SiO2 Support for an Enhanced CO Methanation Performance

Highly-dispersed Ni-NiO nanoparticles was successfully anchored on an SiO2 support via a one-pot synthesis and used as heterogeneous catalysts for CO methanation. The as-obtained Ni-NiO/SiO2 catalyst possessed a high Ni content of 87.8 wt.% and exhibited a large specific surface area of 71 m2g−1 with a main pore diameter of 16.7 nm. Compared with an H2-reduced Ni-NiO/SiO2 (i.e., Ni/SiO2) catalyst, the Ni-NiO/SiO2 displayed a superior CO methanation performance. At the temperature of 350 °C, the Ni-NiO/SiO2 showed a CO conversion of 97.1% and CH4 selectivity of 81.9%, which are much better values than those of Ni/SiO2. After a 50-h stability test, the Ni-NiO/SiO2 catalyst still had an overwhelming stability retention of 97.2%, which was superior to the 72.8% value of the Ni/SiO2 catalyst. Full article
