Interfacial engineering of high-curvature NiFe nanocone arrays for accelerated oxygen evolution via tip-induced electric field and rapid bubble detachment
Mengdi Li, Yubin Yuan, Zongtai Zhou, Feng Chen, Zikang Zhao, Tianshuo Wang, Tianxiao Xie, Yide Luo, Junshuang Zhou, Faming GaoHigh-curvature NiFe nanocone arrays are electrodeposited on nickel foam. Tip-localized electric fields concentrate OH − and superaerophobic interfaces accelerate bubble detachment for enhanced oxygen evolution under high current densities.
