受Pearson软硬酸碱（HSAB）原理的启发，通过选择S2 O32-作为Cu 2 O模板的配位刻蚀剂，优化反应条件，快速制备出具有完整壳层结构和不同尺寸的均匀非晶态Ni（OH）（2）纳米盒。研究发现，不仅溶剂体系，而且表面活性剂的使用是至关重要的纳米盒的制造。例如，Ni（OH）（2）纳米盒表现出对葡萄糖的改善的电化学传感能力，这可能是由于它们的无定形和中空结构特征。
Inspired by Pearson's hard and soft acid-base (HSAB) principle, uniform amorphous Ni(OH)(2) nanoboxes with intact shell structures and various sizes are quickly fabricated by deliberately selecting S2O32- as the coordinating etchant toward Cu2O templates and optimizing the reaction conditions. It is found that not only the solvent system but also the employing of a surfactant is vital for the fabrication of the nanoboxes. Ni(OH)(2) nanoboxes, as an example, demonstrate an improved electrochemical sensing ability for glucose, which might be due to their amorphous and hollow structural features.
