Special Issue Information

Dear Colleagues,

Catalysis is known to be at the heart of oil refining and chemical industry, expanding its application areas to the synthesis of specialty chemicals and pharmaceuticals, where traditional organic synthesis approaches are often applied.

The use of more efficient, green, and sustainable catalytic processes is currently being strongly pursued to improve both the environmental aspects of existing processes and to allow for a switch to renewable resources while also fully utilizing carbon dioxide as a feedstock. Other recent developments in catalysis are also related to the upcycling of plastics and the application of AI to catalyst design and evaluation of catalytic performance.

The editors do not want to limit the scope of the submissions to this Special Issue, entitled ‘Recent Developments in Heterogeneous Catalysis’, and hope that they will focus on various aspects on catalyst preparation, characterization, and fundamental studies, while also covering recent innovations in the field and potential industrial implementations.

The editors invite colleagues working in this field to contribute to this Special Issue with research or review articles.

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 250 words) can be sent to the Editorial Office for assessment.

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. Reactions is an international peer-reviewed open access quarterly 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 1200 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.

This study systematically investigates the role of Ni in Co2SiO4 in a bimetallic (Co2+,Ni2+)2SiO4 olivine-type system and the materials’ catalytic efficiency in a model Heck–Mizoroki coupling reaction. Thus, a series of olivines with varying (Co2+,Ni2+)2SiO4 compositions (0–100% Ni) was synthesised and characterised by ICP-OES, FTIR/Raman, P-XRD and XPS analysis. Ideal mixing of metals was achieved with (49:51) Co:Ni. Catalytic testing revealed distinct conversion vs. time profiles, with the (69:31) Co:Ni olivine exhibiting the best overall performance, combining good reactivity with near-perfect selectivity (>99%) and improved stability. Mechanistic pathways were probed through product scope analysis, reactant–product temporal profiling, leaching and radical scavenging experiments. Results suggest a radical-assisted Heck–Mizoroki mechanism. Spectroscopic data correlated Co2+ and Ni2+ incorporation with M1 and M2 site occupancy, where Ni2+ M2 sites enhanced reactant activation and intermediate stability and Co2+ in the M1 site enhanced product release, though also homocoupling in Co2SiO4. Minimal leaching was observed for all bimetallic catalysts. These findings highlight the tunability of bimetallic olivines for C–C coupling reactions via controlled cation distribution. Full article
