Special Issue Information

Dear Colleagues,

Following the first successful Special Issue on this topic (available here), we are happy to announce a second edition titled “State-of-the-Art of Catalytical Technology in Korea, 2nd Edition”.

Following the devastation cause by the Korean War in 1950, Korea's per capita income at that time was only USD 50, and it was one of the poorest countries receiving food aid from the United Nations. However, through remarkable economic development, today, in 2024, the Republic of Korea has achieved unprecedented economic growth and grown into a country that attracts attention from all countries around the world. Many experts say that the chemical industry has been at the center of economic development in Korea, and catalytical technology is a cornerstone for that success. Diverse types of catalysis, including homogenous and heterogeneous catalysis, biocatalysis, and electrocatalysis, have undergone extremely rapid development for a variety of chemical reactions used in the chemical, fuel, pharmaceutical, and agricultural industries affording a wide range of products in our daily life. In this Special Issue, we are going to focus on the state of the art of catalytic technology in the Republic of Korea and the direction in which we believe we should be heading. All experimental and theoretical results on catalysis from academia and industry are encouraged to be submitted in the form of regular research articles, short communications, or reviews.

If you would like to submit papers to this Special Issue or have any questions, please contact the in-house editor, Ms. Rita Lin (rita.lin@mdpi.com).

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). 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.

Global energy demand escalates the interest in effective and durable catalytic systems for the dry reforming of methane (DRM), a process that converts CO2/CH4 into H2/CO syngas. Porous silica-supported nickel (Ni) catalysts are recognized as a promising candidate due to robust DRM activity associated with the confinement of Ni particles in the mesopores that reduces the catalyst deactivation by carbon byproduct deposits and sintering of active Ni sites. However, the small-sized pore configurations in the mesoporous catalysts hinders the fast mass transfer of reactants and products. A unique combination of the hierarchical nanostructure with macro–mesoporous features of the support is adopted to enhance the catalytic performance via the dual effect of the efficient mass transfer and minimized sintering issue. This study delves into the influence of SiO2 geometry and pore structure on the catalytic performance of Ni-based catalysts. Three types of porous silica supports were synthesized through various methods: (a) hydrothermal-assisted sol–gel for dendritic mesoporous silica (DMS), (b) spray-pyrolysis-assisted sol–gel for spray evaporation-induced self-assembly (EISA) silica, and (c) oven-assisted sol–gel for oven EISA silica. Among the prepared catalysts the hierarchical external nanostructured Ni/DMS showed the superior CH4 and CO2 conversion rates (76.6% and 82.1%), even at high space velocities (GHSV = 360 L∙g−1·h−1). The distinctive macro–mesoporous geometry effectively prevents the sintering of Ni particles and promotes the smooth diffusion of the reactants and products, thus improving catalytic stability over extended reaction periods (24 h). This research highlights the significant impact of macro–mesoporosity revealed in DMS support catalysts on the physicochemical properties of Ni/DMS and their crucial role in enhancing DRM reaction efficiency.
