Nanostructures have drawn great attentions for functional device applications. Among the various techniques developed for fabricating arrayed nanostructures of functional materials, nanostructuring technique with porous anodic aluminum oxide (AAO) membrane as templates becomes more attractive owing to the superior geometrical characteristics and low-cost preparation process. In this mini review, we summarize our recent progress about functional nanostructuring based on perfectly-ordered AAO membrane to prepare perfectly-ordered nanostructure arrays of functional materials toward constructing high-performance energy conversion and storage devices. By employing the perfectly-ordered AAO membrane as templates, arrayed nanostructures in the form of nanodot, nanorod, nanotube and nanopore have been synthesized over a large area. These as-obtained nanostructure arrays have large specific surface area, high regularity, large-scale implementation, and tunable nanoscale features. All these advanced features enable them to be of great advantage for the performance improvement of energy conversion and storage devices, including photoelectrochemical water splitting cells, supercapacitors, and batteries, etc.

为了提高永磁体性能尤其是矫顽力，对气雾化MnAl粉末首次进行了30 s短时间球磨。结果表明，如此短的处理时间加上随后的退火可以高效地得到纳米结构和可控的相变。球磨过程中产生的微应变引起的缺陷与退火过程中形成的β相共同起到钉扎中心的作用，从而提高了矫顽力。研究表明，为了在磁化强度和矫顽力之间达到折中，在铁磁性τ-MnAl相和β相的形成之间找到一个平衡是很重要的。球磨（30 s）和退火后获得的矫顽力高达4.2 kOe (1 Oe = 79.6 A·m–1)，与早期文献报道的球磨时间超过20 h时的矫顽力相当。球磨后粉末的退火温度降低了75 ℃，矫顽力提高了2.5倍，而退火后的气雾化材料的剩磁基本保持不变，为合成各向同性的MnAl基粉末开辟了一条新的途径。
