Abstract
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-2 at a cell voltage as low as 1.15 V with the faradaic efficiency for H2 found to be ∼91%. This study may open avenues for developing novel systems that integrate the IOR with other high-value reduction reactions.
