Special Issue Information

Dear Colleagues,

Currently, the development of Carbon Capture and Utilization (CCU) Technologies plays a key role within the strategies for reducing CO2 emissions, which aim to decelerate global warming. Therefore, the interest in processes that allow the transformation of CO2 into fuels or added-value chemicals has been renewed or reinforced, since their real success and profitability rely on a high performance, including high selectivity and energy efficiency.

Particularly, the recycling of the CO2 generated by main emitters, such as the automotive industry, oil refineries or steel and cement factories, among others, using renewable energy or combining renewable raw materials, is a highly-attractive approach in good agreement with the basis for the transition towards low-carbon productive processes, and circular economy models.

This Special Issue of Chemistry principally focuses on catalytic approaches of chemical and electrochemical transformations of CO2 into fuels and/or high-added value products. Therefore, the design, characterization and catalytic evaluation of new catalysts are included, as well as the use of advanced catalytic analysis by means of in-situ and/or operando approaches and kinetic studies. In addition, the use of catalytic devices, such structured and microstructured reactors or novel reactor designs for catalytic activity measurements during CO2 transformation will also be considered.

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. Chemistry is an international peer-reviewed open access semimonthly 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 1800 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.

Encapsulation of metal nanoparticles is a leading technique used to inhibit the main deactivation mechanisms in dry reforming of methane reaction (DRM): Carbon formation and Sintering. Ni catalysts (15%) supported on alumina (Al2O3) and ceria (CeO2) have shown they are no exception to this analysis. The alumina supported catalysts experienced graphitic carbonaceous deposits, whilst the ceria showed considerable sintering over 15 h of DRM reaction. The effect of encapsulation compared to that of the performance of uncoated catalysts for DRM reaction has been examined at different temperatures, before conducting longer stability tests. The encapsulation of Ni/ZnO cores in silica (SiO2) leads to advantageous conversion of both CO2 and CH4 at high temperatures compared to its uncoated alternatives. This work showcases the significance of the encapsulation process and its overall effects on the catalytic performance in chemical CO2 recycling via DRM. Full article
