文摘

By rationally designing superhydrophobic electrodes with different underwater wetting states, it is revealed that only the underwater Wenzel-Cassie coexistent state shows the clearly enhanced ability in catalyzing the oxygen reduction reaction, a typical underwater gas-consuming reaction at electrode. It is proposed that the maximizing and stabilizing the liquid/gas/solid triphase interface, endowed by the underwater Wenzel-Cassie coexistent state, plays a rather crucial role.
