摘 要：For carbon-free electrochemical fuel formation,the electrochemical cell must be powered by renewable *** solar-powered H_(2) fuel from water typically requires multiple photovoltaic cells and/or junctions to drive the water splitting *** of the lower thermodynamic requirements to oxidize ammonia compared to water,solar cells with smaller open circuit voltages can provide the required potential for ammonia *** this work,a single perovskite solar cell with an open-circuit potential of 1.08 V is coupled to a 2-electrode electrochemical cell employing hybrid electroanodes functionalized with Ru-based molecular *** device is active for more than 30 min,producing N_(2) and H_(2) in a 1:2.9 ratio with 89%faradaic efficiency with no external applied *** work illustrates that hydrogen production from ammonia can be driven by conventional semiconductors.
