Making syngas electrocatalytically using a polypyridyl ruthenium catalyst.
Electrocatalytic reduction of carbon dioxide to carbon monoxide and of water/weak acids to hydrogen by a class of polypyridyl ruthenium complexes both occur by well-defined mechanisms involving common intermediates. Based on available mechanistic insight, conditions have been found for competitive electrocatalytic reduction of CO2-H2O-H2PO4(-) mixtures by a single metal complex catalyst to give syngas products with the H2 : CO ratio controllable by controlling the composition of the solutions.
