Muon Spectroscopy and Artificial Hydrogenases (RB920382)

DOI

The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed at practical rates at moderate temperatures. Currently platinum is the preferred electrocatalyst in reversible hydrogen fuel cells. The supply of this metal is limited and in the long term unsustainable. The metal-sulfur catalytic sites of hydrogenases are built from abundant elements and can catalyse hydrogen evolution or uptake at rapid rates comparable to platinum. We have developed artificial molecules that mimic the function of hydrogenase in a catalytic cycle. We wiah to explore the possibility of using muon spectroscopy to determine the structure and dynamics of hydrogen atoms associated with these molecules during the catalytic cycle by first studying the reactions with muonium.
