A Self-Supported Coral-like Pt/SnO<sub>2</sub>/Nb<sub>2</sub>O<sub>5</sub>/Nb Electrode: A Bifunctional Electrocatalyst for Membrane-Free Green H<sub>2</sub> Production via Coupling Ethanol Selective Electrooxidation

A Self-Supported Coral-like Pt/SnO<sub>2</sub>/Nb<sub>2</sub>O<sub>5</sub>/Nb Electrode: A Bifunctional Electrocatalyst for Membrane-Free Green H<sub>2</sub> Production via Coupling Ethanol Selective Electrooxidation

The production of green hydrogen via water electrolysis faces challenges due to the sluggish oxygen evolution reaction at the anode. In this study, we developed a self-supported bifunctional Pt/SnO<sub>2</sub>/Nb<sub>2</sub>O<sub>5</sub>/Nb electrocatalyst capable...
