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, and is 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.
