摘要
三维金属纳米花有一系列优越的理化性能,由于结构特异,在催化、传感上应用广泛,还可以用于制作微观尺度的器件,引起了人们极大的兴趣。从选择性刻蚀、模板引导、种子生长法和动力学控制等方面,介绍了近期在三维金属纳米花合成领域取得的进展,并简述了这种纳米粒子在催化以及电催化方面的应用。
Three-dimensional mental nanof lowers have a series of superior physical and chemical properties. Due to their structural specificity, they are widely used in catalysis and sensing, and can also be used to fabricate microscale devices, which has aroused great interest. In this paper, recent advances in the field of three-dimensional mental nanoflowers synthesis will be introduced from the aspects of selective etching, template guiding, seed growth and kinetic control, and the application of this nanoparticle in catalysis and electrocatalysis will be briefly described.
