A single‐pot electrolytic synthesis of hydrogen and carbon fuels is achieved through the use of a mixed, hydroxide/carbonate electrolyte, nickel anode (generating O2), and nickel or steel cathode (generating graphite and hydrogen). Low hydroxide fractions in the electrolyte ensure efficient carbon formation, while high fractions form only H2 at the cathode; added barium and lithium salts ensure effective nickel anode stability.

A single pot electrolytic synthesis of hydrogen and carbon fuels is achieved through the use of a mixed, hydroxide/carbonate electrolyte, a nickel anode (generating O2), and a nickel or steel cathode. In article number 1401791 Stuart Licht and co‐workers report that the generation of hydrogen and carbon fuels is driven with conventional power or efficiently generated from sunlight using solar thermal and electric (CPV) energy as STEP (solar thermal electrochemical process) fuels.

The Haber-Bosch process to produce ammonia for fertilizer currently relies on carbon-intensive steam reforming of methane as a hydrogen source. We present an electrochemical pathway in which ammonia is produced by electrolysis of air and steam in a molten hydroxide suspension of nano-Fe2O3. At 200°C in an electrolyte with a molar ratio of 0.5 NaOH/0.5 KOH, ammonia is produced at 1.2 volts (V) under 2 milliamperes per centimeter squared (mA cm-2) of applied current at coulombic efficiency of 35% (35% of the applied current results in the six-electron conversion of N2 and water to ammonia, and excess H2 is cogenerated with the ammonia). At 250°C and 25 bar of steam pressure, the electrolysis voltage necessary for 2 mA cm-2 current density decreased to 1.0 V. [ABSTRACT FROM AUTHOR]
