The electrochemical reduction of carbon dioxide (CO2) is a key technology to combat global climate issues. By utilizing renewable energy, we can convert greenhouse gases into value-added commodity chemicals. While there has been a growing number of CO2 research in recent years, there are still many unanswered fundamental questions and engineering challenges. With this collection, we encourage scientists from different academic backgrounds to explore these remaining challenges in the CO2 electrochemical reduction reaction and provide a forum for the CO2 community to share their latest research results. We welcome all submission of original research articles, reviews and perspectives related to the theme of CO2 electrocatalytic reduction.

This Guest Edited Collection aims to bring together research focused on polymeric transformations mediated by organocatalysts, primarily focusing on organomediated polymeric transformations, but also other sustainable catalysts such as work on biocatalytic polymerizations and work using earth abundant sustainable metals, as well as new perspectives on the depolymerization of polymers synthesized by the above or related methodologies.

This cross-journal Collection brings together the latest developments in electrodes, electrolytes, and battery components used in aqueous and non-aqueous sodium-based battery applications.

This Guest Edited Collection aims to bring together research at the intersection of systems chemistry and coacervation. We welcome both experimental and theoretical studies.

This Collection aims to offer insights and inspiration for the development of fluorescent probes for biological imaging and sensing. We encourage submissions that focus on design strategies and rational response mechanisms, electronic and spectral characteristics, and biological applications as powerful tools for chemical biology.

In this collection, we want to highlight research that focuses on fragments in drug discovery. Have you found validated fragment hits for a new disease target? Maybe they unlocked an unreported enzyme mechanism? Were you able to develop a method that is useful for fragment-based drug discovery? Perhaps you found a hit that made it to clinical trials? We invite all scientists who work with fragments in the context of drug discovery to submit their interesting fragment stories. We look forward to hearing all about them.

This collection encourages submissions related to hydrogen evolution catalysis, particularly where hydrogen gas is the primary product. This is a cross-journal partnership between the Energy Materials team at Nature Communications with Communications Chemistry, Communications Engineering, Communications Materials, and Scientific Reports. We seek studies covering a range of perspectives including materials design & development, catalytic performance, or underlying mechanistic understanding. Other works focused on potential applications and large-scale demonstration of hydrogen evolution are also welcome.

Electrochemical interfaces are complex reaction fields of mass transport and charge transfer. They are the centerpiece of energy storage and conversion devices — such as batteries, supercapacitors, fuel cells, solar cells, or electrolyzers — as well as electrochemical syntheses. This Guest Edited Collection brings together the latest works on electrochemical interfaces.

Supramolecular polymers have emerged as an exciting class of materials over the last three decades. This Collection aims to highlight recent progress in the field of supramolecular polymers, including strategies and mechanisms for their controlled polymerization, approaches to characterization and modelling, study of their physical and mechanical properties, and demonstration of their potential applications.

This Collection aims to bring together cutting-edge research and innovative solutions addressing the resilience and performance of batteries under extreme conditions.

This Collection aims to bring together the latest progress in the synthesis, characterization, and functionalization of covalently bonded nanomaterials fabricated by the on-surface synthesis approach, as well as highlighting advances in the synthesis of coordination polymers, macrocycles and other compounds obtained on surfaces.

To mark the International Day of Women and Girls in Science, the Editors of Communications Chemistry are pleased to launch a Collection celebrating women in chemistry, showcasing excellent research from women corresponding authors who have recently published in the journal. The Collection also includes articles focused on promoting gender equity in STEM.
