Advanced Multi-Metal and Interface-Engineered Catalysts for Circular Carbon Conversion

Dear Colleagues,

Circular carbon conversion has emerged as a pivotal strategy to mitigate anthropogenic carbon emissions, promote carbon neutrality and achieve sustainable utilization of carbon resources (e.g., CO₂, biomass and waste plastics). Catalysts are the core driving force behind efficient circular carbon-conversion processes, and the rational design of catalyst structures—particularly multi-metal synergism and interface engineering—has become a frontier focus to break through the bottlenecks of low activity, selectivity and stability in current catalytic systems.

This Special Issue aims to showcase cutting-edge research advances in advanced multi-metal catalysts (e.g., alloy, intermetallic compounds and bimetallic/trimetallic composites) and interface-engineered catalytic materials (e.g., defect-rich interfaces, metal-support interactions and heterojunction interfaces) for circular carbon conversion. We welcome original research articles, reviews and communications that address key topics including, but not limited to:

• Design, synthesis and structural characterization of multi-metal/interface-engineered catalysts;
• Catalytic mechanisms of carbon-conversion reactions (e.g., CO₂ hydrogenation, biomass valorization, catalytic pyrolysis of waste carbon and reforming reactions);
• Regulation of catalytic performance via interface engineering (e.g., enhancing reactant adsorption, optimizing reaction pathways and suppressing side reactions);
• Scale-up applications and industrial feasibility of advanced catalysts in circular carbon systems.

By integrating interdisciplinary insights from materials science, catalysis and carbon management, this Special Issue seeks to facilitate academic exchanges, accelerate technological innovation and provide a platform for researchers to share breakthroughs in advancing sustainable circular carbon conversion.

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. 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 2200 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.
