Enhanced H production assisted by anodic iodide oxidation using transparent tin oxide-based electrodes.

In this work, the direct use of transparent conducting oxides (TCOs) as cost-efficient anodes for the iodide oxidation reaction (IOR) is explored. Energy-saving hydrogen production assisted by the IOR is demonstrated using a hybrid water electrolysis system with FTO as the anode and Pt-wire as the cathode. The hybrid system delivers 10 mA cm at a cell voltage as low as 1.

Iodide-assisted energy-saving hydrogen production using self-supported sulfate ion-modified NiFe(oxy)hydroxide nanosheets.

Hybrid water electrolysis (HyWES) with iodide oxidation as non-OER for energy-saving H production is demonstrated using self-supported sulfate ion modified Ni,Fe(oxy)hydroxide as the anode. The sulfate ions adsorbed on the catalyst show a promoting effect in achieving high electrochemical activity. The HyWES requires a voltage as low as 1.
