Chemistry for Sustainability

We use coordination chemistry to tackle societal issues ranging from the elimination of plastic waste and CO2 levels to the development of new metal-based agents for use in medical imaging and anti-cancer therapy.

The Challenge

Chemistry is central to the manufacture of much of what we use in everyday life. By manipulating the structure of known compounds or by designing new compounds, it is possible to manufacture new materials with enhanced properties. We are using this strategy to make environmentally friendly materials, some of which are use CO2 as a feedstock.

Environmental monitoring traditionally relies on samples being taken by a specialist and brought to laboratory facility for analysis. Data we have available is often rather sporadic and we know little about trends and dynamics of geochemicals, nutrients and pollutants in our environment.

The Approach

The approach is a collaborative research with Chemistry at the heart of all activities. Chemistry is the vital discipline thanks to which novel plastics are created.

We use coordination chemistry to tackle societal issues ranging from the elimination of plastic waste and CO2 levels to the development of new metal-based agents for use in medical imaging and anti-cancer therapy. This is accomplished by manipulating the environment surrounding various metal centres both in terms of the sterics and the electronics of the metal bound ligands present.

Chemists in Hull are also developing new analysis methods to measure and monitor levels of geochemicals, nutrients, and pollutants in the environment, often working with Citizen Scientists.

 

Impact

We have created new biodegradable plastics as alternatives to traditional plastics, which take centuries to degrade. We have also established links with the circular economy . We hope our research will contribute to a better environment by designing.

We are developing chemical analysis systems for monitoring on-site. High-frequency chemical sensing will allow us to develop a fundamental understanding of the fate of pollutants in our surroundings. Together with computer scientists we can start to predict trends and decide where to deploy mitigation efforts.

Projects

Water droplet

Sullied Sediments

Chemicals found in household products, including toothpaste, soaps and common drugs are threatening Britain's waterways by accumulating in rivers and canals. This Europe-wide project aims to offer solutions to improve the removal of the chemicals from waste water treatment plants, before they enter the waterways.
