This project will produce new, high performance, surface active ionic liquids. Surface active ionic liquids are pure salts in which one of the ions is based on a surfactant molecule. Surface active ionic liquids are much more effective than conventional electrolytes for some applications, but only at elevated temperature; at low temperature, ion dynamics are too slow. We will use cutting edge techniques to probe ion dynamics in surface active ionic liquids in the bulk and at electrode surfaces, and use this to elucidate rules for the rational design of new surface active ionic liquids with fast dynamics at low temperature, towards their use at room temperature in diverse areas; this project will target capacitors and gas sensors.

From plastics to pharamaceuticals, chemists rely extensively on expensive and environmentally damaging solvents and reactants. In water, greener and cheaper electricity-driven reactions currently suffer from low velocity and poor selectivity. The project aims to develop the science of on-water electrochemistry, to make electricity-driven organic reactions in water viable. Demonstrating that for electrochemical reactions, rates and selectivities increase on water’s surface rather than in its bulk will remove fundamental constraints on the viability of aqueous electro-synthesis – moving beyond current reactor designs to transform our view of electrochemistry and improve the sustainability of the chemical industry.Read moreRead less

Summary
Combination of electrochemistry with sono to destroy and detoxify PFAS. Previously the major means of dealing with per- and poly-fluoroalkyl substances (PFAS) is by adsorption, to collect and remove PFAS from contaminated sites. However, PFAS still exist, non-degraded and waiting for destruction. Targeting slurry waste from current remediation / adsorption plants, this project aims to efficiently degrade PFAS by combining electrochemical oxidation with sono-chemistry to enhance degradation capac ....Combination of electrochemistry with sono to destroy and detoxify PFAS. Previously the major means of dealing with per- and poly-fluoroalkyl substances (PFAS) is by adsorption, to collect and remove PFAS from contaminated sites. However, PFAS still exist, non-degraded and waiting for destruction. Targeting slurry waste from current remediation / adsorption plants, this project aims to efficiently degrade PFAS by combining electrochemical oxidation with sono-chemistry to enhance degradation capacity, to accelerate PFAS desorption / transportation from slurry waste, to avoid electrode fouling and to detoxify PFAS. The expected outcome of this project is to clean up contaminated sites, including PFAS / precursors and other persistent organic pollutants, leading to significant environmental benefits.Read moreRead less

This project aims to create a new class of electrocatalysts with architectures inspired by enzymes. Electrocatalysts are the backbone of the modern energy economy. In the new electrocatalysts developed by the project, the intention is the active sites will be spatially separated from the bulk solution by nanopores, as enzymes do. This architecture allows the reaction environment to be altered from the bulk solution, active transport of species to the active site and cascade reactions to be performed. This should give advantages in activity, selectivity and the ability to perform multistep reactions. The intended outcomes are better performing hydrogen fuel cells and more effective conversion of carbon dioxide into useful organic compounds.Read moreRead less

This project aims to develop and implement an alternative approach to the current methods of monitoring of oxygen and toxic gas levels. The aim is to use novel gelled electrolytes based on ionic liquids and polymers, combined with miniaturised sensor devices, to create a robust membrane-free and spill-less design. Amperometric gas sensors are commonly employed to monitor oxygen and toxic gas levels, but the technology used is still based on a 1950s design. The expected outcome of the project is to make fundamental advances in the design of materials that are not affected by humidity changes and which impart selectivity towards particular gases. This will provide the basis for a new generation of low-cost, miniaturised, selective sensors for use in applications such as wearable toxic gas sensors, and as leak detectors on hydrogen-powered vehicles.Read moreRead less

This project aims to create new science that will enable the development of low-cost, miniaturised electrochemical sensors based on poly-ionic liquids. The chemistry of the materials will be tuned to selectively detect hazardous pollutants to enable trace concentration detection at analytically relevant levels. Fundamental behaviour of gases and solid contaminants dissolved in poly-ionic liquid/ionic liquid membranes will be uncovered, and their performance for sensing in real environments will be examined. It is expected that these advances will transform detection methods by taking sensing out of the lab and in to the hands of the everyday person, giving rapid and accurate knowledge about the concentration of hazards in the environment.Read moreRead less
