| ABSTRACT |
|
To date, many methods have been suggested to improve the performance of materials in various applications by applying new physical and chemical properties at the nanometer scale in the form of nanodots, nanowires, and nanofi lms. However, most of the proposed methods are diffi cult to apply to industrial settings due to their size limitations. In that sense, the realization of 3D nanostructured materials is signifi cant for practical use of nanotechnology. The continuous 3D nanostructuring insures the maximum utilization of materials effi ciency and improves the stability through well-ordered structures. In this respect, 3D nanostructures of materials can be useful for energy conversion applications such as thermoelectric, piezoelectric, and electrocatalytic applications. Herein, we briefl y overview 3D nanofabrication methods to convert the materials in the 3D nanostructures, followed by a review on the advantages of 3D ordered nanoelectrodes for high-performance energy conversion applications. |
