Graphitic carbon nitride quantum dot decorated three-dimensional graphene as an efficient metal-free electrocatalyst for triiodide reduction

We demonstrate a new strategy for the development of graphitic carbon nitride quantum dots decorated on three-dimensional graphene as an efficient electrocatalyst for triiodide reduction. The special architecture of these hybrids endows them with an abundance of exposed sites and multiple pathways of charge and mass transport, resulting in synergistically enhanced electrochemical performance.
