“…Electrochemical conversion of waste biomass offers a fuel-exible route to sustainable, net-zero greenhouse gas emissions production of hydrogen whilst valorising waste biomass feedstocks. In recent years, the examination of polyoxometalate (POM) materials as catalysts, 5,6 which can digest biomass, has been undertaken. POM materials comprise large, polyanionic MO x clusters, in which M = transition metals such as Mo, W and V, 5,7 as well as a variety of cations.…”
