Assembling micro‐/nanostructured arrays on conducting substrates allows the integration of multiple functionalities into modern electronic devices. Herein, a novel self‐sustained cycle of hydrolysis and etching (SCHE) is exploited to selectively synthesize an extensive series of metal oxide micro‐/nanostructured arrays on a wide range of metal substrates, establishing the generality and efficacy of the strategy. To demonstrate the potential application of this method, the as‐prepared NiO porous nanobelt array was directly used as the anode for lithium‐ion batteries, exhibiting excellent capacity and rate capability. Conclusively, the SCHE strategy offers a systematic approach to design metal oxide micro‐/nanostructured arrays on metal substrates, which are valuable not only for lithium‐ion batteries but also for other energy conversion and storage systems and electronic devices at large.
