Electrocatalytic water splitting

Hydrogen appears as a next-generation clean energy source to replace fossil fuels. One of the most promising ways to produce hydrogen is electrochemical water splitting. To address the low efficiency of hydrogen production, a novel approach is needed to achieve a breakthrough in a highly efficient catalyst system. We now focus on developing efficient water-splitting catalysts based on transition metal oxides, hydroxides, and layered double hydroxides. Synthesized catalysts can be used in an anion-exchange membrane water electrolyzer (AEMWE) stack cell system to produce large amounts of hydrogen fuel. We aim to enhance the AEMWE stack cell efficiency by systematically investigating the relationships among catalysts, membranes, and all cell components.
