About this collection

We are delighted to share with you a selection of the papers presented at our Faraday Discussion on Designing Nanoparticle Synthesis for Catalysis which took place in London, UK in May 2018. The final versions of all the articles presented and record of the live discussions are now available in the published Faraday Discussions volume 208.

Heterogeneous catalysis is a core area of contemporary physical chemistry posing major fundamental and conceptual challenges, and nanoparticles are pivotal components of many successful heterogeneous catalysts. For example, commercial Fischer–Tropsch catalysts require supported cobalt nanoparticles that are 6 nm in diameter for optimal performance. Nanoparticles are ubiquitous in many heterogeneous catalysts and this Faraday Discussion has explored the modern methods being used to design, synthesise and characterize nanoparticles, and how these bridge across the disciplines of physical science and chemical engineering. The core aim of the discussion was to develop a fundamental understanding of these crucial aspects of catalytic science, especially relating to nanoparticle synthesis and its use in catalytic reactions, knowledge of which is essential for the design of new catalysts.
