Our group developed a facile photochemical way to synthesize Iridium dinuclear heterogeneous catalyst (DHCs) and for the first-time report that both side-on and end-on binding are possible for Ir DHCs supported on different substrates. Our finding is built upon recent advances aimed at studying single-atom catalysts (SACs) but takes a crucial step forward. It provides a great material platform to study reactions that would require more than one active site.

Lithium Ion Batteries

Development of the Li-O2 battery as a practical energy storage technology has been underpinned by the lack of a stable electrolyte to enable reversible conversion between O2 and Li2O2, given that previous applied organic electrolytes all show reactivity toward reactive oxygen species. Our group demonstrates that this issue can be solved with a water-in-salt electrolyte that contains no organic solvent molecules. The net result is a highly effective electrolyte that enables stable Li-O2 battery operations up to 300 cycles.
