Abstract

Abstract Two-dimensional (2D) quantum dots (QDs), an exciting and emerging quantum confined systems, have shown promising applications including sensors, batteries, white light-emitting diodes (WLEDs), supercapacitors, etc. In this review, we have summarized the most recent progress on 2D QDs. The synthesis routes, photoluminescence mechanism, as well as emerging energy and environmental applications are discussed. This review will function as a one-stop point to understand the state-of-the-art advancement in 2D QDs and is expected to inspire scientists and engineers to leverage 2D QDs in a diverse of energy- and environmental-related fields.
