Abstract

Two-dimensional transition metal dichalcogenides (2D TMDs) possess a rich set of extraordinary structural, chemical, electrical, and optical properties unattainable with any traditional materials. A large number of these properties are particularly suitable for energy generation/conversion applications, which renders unprecedented yet tremendous opportunities for addressing the multi-faceted demands of up-coming energy technologies. Heterogeneously integrating 2D TMDs with other energy materials is projected to improve the performance of existing energy devices and/or achieve unconventional functionalities in a highly synergic manner, which cannot be catered by stand-alone 2D TMDs. In this article, we present a comprehensive review on the up-to-date progress in the development of 2D TMD hybrid materials for a variety of energy applications. This review focuses on addressing how the incorporation of 2D TMDs can help manipulate the functionalities of conventional energy materials to achieve targeted and improved energy device performances. An overview of the recent progress in the development of various 2D TMD hybrid materials and their fabrication strategies is presented, followed by a survey on various energy devices based on these materials and their performance comparison. Current challenges associated with material developments are discussed, and forward-looking outlooks assessing unexplored research areas are also suggested.
