Atomically-thin WO3/TiO2 heterojunction for supercapacitor electrodes developed by atomic layer deposition
Source abstract
Abstract
Abstract In this study two-dimensional (2D) WO 3 /TiO 2 heterojunction developed by atomic layer deposition (ALD) technique has been demonstrated for the first time for supercapacitor (SC) electrodes. This 2D heterojunction has a uniform thickness of ~ 12 nm with relatively rough surface. The electrode based on WO 3 /TiO 2 heterojunction shown excellent super-capacitive behaviors with high specific capacitance up to 625.53 F g -1 at the current density of 1 A g -1 and long-term stability of 97.98% over 2000 cycles. The present work could represent the general approach towards the large-scale fabrication of 2D heterojunction electrodes for high-performance SCs.
