Carbon nanodots (C-dots) with sizes below 10 nm are attracting attention for a spectrum of environmental and energy applications, ranging from heterogeneous chemical catalysis, photocatalysis, electrocatalysis to energy storage such as batteries and/or capacitors. Here, we present an account of the recent progresses on C-dots from our research activities [see references]. We start with the introduction of the preparation methods and typical structures of C-dots, followed by a discussion of their chemical and physical properties. We then focus on their environmental and energy applications, and the design of catalysts and functional materials from C-dots. The following applications are demonstrated: Direct use of C-dots for photo- and electro-catalysis, as well as for the design of (3) photocatalysts, (4) photoelectrochemical catalysts, (5) electrocatalysts, and (6) nanocomposite functional materials. Finally, we provide an outlook of C-dots-based materials for environmental and energy applications.
