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 utilized in an anion-exchange membrane water electrolyzer (AEMWE) stack cell system to produce a large amount of hydrogen fuel. We aim to enhance the AEMWE stack cell efficiency by systematically investigating the relationships among catalysts, membranes, and all cell components.
