Recent review on self-supported one-dimensional core/shell nanostructures based on WO3 for enhanced electrochromism

Abstract

Self-supported one-dimensional (1D) core/shell nanostructures (SS1DCSNs) offer multiple inherent advantages in the field of electrochromism, establishing them as a prominent emerging technology. This review categorizes SS1DCSNs into self-supported 1D nanostructures and core/shell structures, providing an in-depth analysis of their various advantages in electrochromism. Tungsten trioxide (WO₃) has garnered significant attention owing to its exceptional electrochromic performance, considered one of the most promising materials in this domain. With integration and analysis of existing research, this review delivers a comprehensive overview of the current state of development and future research prospects of WO₃-based SS1DCSNs in electrochromism.
