Switchable and stereocontrolled photoredox catalysis. This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light.

This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light. An integrated experimental and computational approach will be used to design potent visible-light photocatalysts that retain the advantages of standard photoredox catalysis but with the added ability to intercept and, thus control, reactive intermediates in situ. This will enable the control of stereochemistry in photoredox reactions – not possible with standard catalysts - and establish other useful synthetic transformations. These strategies will make it easier to prepare valuable classes of organic molecules – efficiently, safely, and cost-effectively.

The chemical utilisation of CO2 is one of two major strategies in achieving net negative CO2 emissions mitigating the environmental and socioeconomic damage of global warming. Inspired by the ability of natural enzymes to efficiently utilise molecules like CO2, this project aims to develop original metal-based catalysts as enzyme mimics for the efficient transformation of CO2. It will deliver practical strategies to transform CO2 into value-added materials permanently removing it from the atmosphere. Project outcomes are expected to enhance industry’s capacity to use CO2 as a feedstock chemical for the production of fuels and materials, providing significant economic and environmental benefits through CO2 upcycling and recycling.Read moreRead less

Changes in the ocean's biological pump: innovative models and diagnostics. This Project aims to quantify how the ocean’s biological pump, which exports newly formed organic matter into the ocean interior, responds to environmental change. The biological pump is a key control on the global carbon and oxygen cycles, and hence on the viability of marine life. New, efficient numerical models will be developed and analysed with highly innovative mathematical methods. Expected outcomes are optimised predictive models and a new understanding of the possible future evolutions of the ocean carbon cycle, acidification, and oxygenation. This should provide significant benefits such as predictions of future ocean health, identification of processes that are sensitive to change, and strategies for marine resource management.Read moreRead less
