Dimension-tailored functional graphene structures for energy conversion and storage.

Functional graphene nanostructures of interesting physical and chemical properties have been attracting lots of research effort. In this feature article we focus on some of the recent work of dimension-tailed graphene contributed by us and others, and review the current trends in the tunable and controllable preparation of functionalized graphene architectures ranging from zero-dimensional quantum dots to three-dimensional networks. Additionally, recent progresses in applying these dimension-tailored graphene structures in energy conversion and storage are explicitly discussed, particularly in devices such as solar cells, actuators, fuel cells, supercapacitors, etc., presenting the great prospect of functional graphene structures in this dynamic research field.
