The electrocatalytic hydrogenation of aldehydes on transition metal catalysts in water was investigated. By combining electrochemical investigations with physicochemical characterization of catalysts, the adsorption of hydrogen on Pt is found to be affected by external electric potential and electrolyte composition. Thus, hydrogenation rates and selectivity of reactions can be tuned. Increasing the destabilization of hydrogen bound to the metal surface leads to higher reaction rates, but also a decreased current efficiency.
