Seawater splitting by complicated electrocatalytic processes is promising for hydrogen evolution. Here we present a series of robust electrodes by electrodepositing RuCo and RuCoMox alloys on Ti foil substrates for hydrogen evolution from seawater splitting. The preliminary results demonstrate that Ti foil supported RuCo and RuCoMox alloy electrodes require overpotentials of similar to 387 and similar to 550 mV to drive the hydrogen evolution reaction (HER) at a benchmark current density of 10 mA cm(-2), respectively. Moreover, the resultant Ti foil supported RuCoMox electrode shows excellent stability under persistent operation at a constant current density of -1.2 V over 12 h. (C) 2016 Elsevier Ltd.
