Triplet excited states
Creating advanced metal catalysts for artificial photosynthesis to improve water oxidation and CO2 reduction.
The intense study of proton coupled multi-electron transfer reactions of, and those catalysed by electronically excited states of transition metal complexes is the focus of this Joint Lab.
This project focused on developing advanced metal catalysts for artificial photosynthesis, which oxidise water and reduce carbon dioxide efficiently under thermal and photochemical conditions. This study explored phosphorescent transition metal complexes with long-lived triplet excited states for solar energy conversion. These complexes, particularly those incorporating inexpensive and biocompatible metals like iron, are designed to undergo proton-coupled multi-electron transfer reactions, essential for water oxidation and CO2 reduction. The research also explored the integration of these metal complexes with nanocarbon and semiconductor materials for enhancing CO2 conversion, exploring alternative energy sources.
