Porous MoO2 Nanosheets as Non‐noble Bifunctional Electrocatalysts for Overall Water Splitting

A porous MoO2 nanosheet as an active and stable bifunctional electrocatalyst for overall water splitting, is presented. It needs a cell voltage of only about 1.53 V to achieve a current density of 10 mA cm(-2) and maintains its activity for at least 24 h in a two-electrode configuration.
