Distinguishing between homogeneous and heterogeneous hydrogen-evolution catalysis with molecular cobalt complexes

Abstract

Molecular proton-reduction catalysts can decompose under the acidic conditions required for hydrogen evolution, resulting in formation of secondary metal-containing materials. Using an electrochemical quartz crystal microbalance (EQCM), we report a new method for probing electrodeposition of catalytically active heterogeneous material from molecular precursors. The data collected suggest that EQCM can provide a direct measure of the homogeneity of molecular proton-reduction catalysts over short timescales.
