The main objective of this congress is to bring researchers together to discuss the progress of operando methodologies, i.e. characterization of functional materials in their working state.

The conference is organized by the Competence Centre for Catalysis at Chalmers University and will cover all aspects of catalysis within heterogeneous catalysis, homogeneous catalysis and biocatalysis, including thermal catalysis, electrocatalysis and photocatalysis.

Welcome to ICCDU 2026 WashU is delighted and honored to welcome esteemed academic, research, and industrial professionals from around the world to the 23rd International Conference on Carbon Dioxide Utilization (ICCDU 2026), to be held July 6–10, 2026 in St. Louis, Missouri, hosted by Washington University in St. Louis (WashU). ICCDU is the premier international forum dedicated to the carbon circular economy, bringing together leading researchers, industry innovators, policymakers, and entrepreneurs to exchange knowledge, share breakthroughs, and accelerate practical solutions for carbon utilization. ICCDU 2026 will spotlight advances in catalysis, electrochemical and biological conversion, systems integration, and pathways toward scalable and economically viable CO₂ utilization technologies. We look forward to welcoming you to St. Louis for an inspiring exchange of the latest scientific results, inspiring discussions, and the formation of new collaborations advancing CO₂ as a resource—addressing one  of the most pressing challenges of our time. Early registration is encouraged to support conference planning and logistics. Please view the timeline below for key dates and upcoming deadlines.  

Stimulating closer ties between academia and industry and encouraging young researchers in the field of catalysis are the central concepts of this conference. This conference should greatly contribute to exchanging new ideas and technologies, and promoting developments of new outstanding catalysts and systems under the scope, that catalysis is a highly and eagerly demanded technology in industries and for sustainable society, and drives innovation in many other fields. Papers on the following topics are welcome.
