The Section “Computational Catalysis” of Catalysts (ISSN: 2073-4344) is dedicated to publishing original computational-based investigations within the broad field of catalysis. This includes the development of new computational techniques and screening methods, as well as the rigorous application of current computational tools for discovering new catalysts, reaction mechanisms, or catalytic processes.

Computational catalysis serves as a crucial link between theory and experiment in chemistry. By bridging the gap between computational modeling and laboratory practice, it promotes meaningful collaboration between experimentalists and theoreticians. The advances in modeling are linked to, and systematically validated by, numerous old and new experimental insights, fostering fruitful cooperation between different chemistry groups.

Catalysts (ISSN: 2073-4344) has launched the Section “Catalytic Materials”. Catalytic materials exist in several forms and can be prepared using various methods involving different schemes and protocols. They can also be applied in many fields, such as environmental and sustainable catalysis, biomass valorization, renewable fuels production, CO₂ recycling, synthetic chemistry, gas storage/capture, drug delivery, catalysis, photocatalysis, chemical sensing, etc. The present Section on catalytic materials aims to advance our understanding of heterogeneous catalysis, offering a comprehensive investigation of physicochemical properties, catalytic application, and the structure–activity relationship.

As they are of open access format, you have free and unlimited access to the full text of all the articles published in our journal. We welcome you to read our top cited papers published in 2023 and 2024:

MDPI will be attending ECIS UK Colloids Conference 2025, which will be held from 7 to 12 September 2025 in Bristol, UK.

The ECIS UK Colloids Conference is the flagship event of the European Colloids and Interface Society (ECIS). Its 39th edition will be jointly held with the 5th UK Colloid Science Conference in the historical city centre of Bristol.

The joint conference aims to attract more than 700 established and early career scientists from academia and industry—from the UK, EU, US, Australia, China, and further across the globe. The conference topics are broad, ranging from fundamental studies to innovation-oriented research, providing a stimulating platform for the delegates to present and discuss the latest multidisciplinary research and applications in the field of colloid and interface science.

There will also be special sessions, such as those on scattering and aerosols, as well as a session reflecting the leadership in colloid research at Bristol University by Brian Vincent and Terry Cosgrove for some 40 years from the early 1970s.

The following MDPI journals will be represented at the conference:

• Colloids and Interfaces;
• Surfaces;
• Liquids;
• Fluids;
• Coatings;
• Catalysts;
• Macromol;
• Physchem.

If you are planning to attend this conference, please feel free to stop by our booth and start a conversation with us. Our delegates look forward to meeting you in person and answering any questions that you may have.
