A superhydrophobic pillar-structured electrode leads to uncommon electrochemical behavior. The anti-wetting reaction surface restricts the contact between electrolyte and electrode to the pillar tops, as a result of trapped air pockets in the gaps between pillars. The electrochemical reaction occurs mainly at the solid/liquid/gas triphase interface, instead of the traditional solid/liquid diphase surface, yielding unique edge-growth structures - for example gold microflowers - on the top of each pillar.
超疏水柱状电极导致了异常的电化学行为。由于在柱体之间的间隙中捕获了空气口袋，这种防湿反应表面将电解质与电极之间的接触限制在柱体顶部。电化学反应主要发生在固/液/气三相界面处，而不是传统的固/液二相表面，从而在每个柱体的顶部产生独特的边缘生长结构，例如金微花。
