The development of new promising metal-free catalysts is great significance for the electrocatalytic hydrogen evolution reaction (HER). Herein, a rationally assembled three-dimensional (3D) architecture 1D graphitic carbon nitride (g-C3N4) nanoribbons with 2D graphene sheets has been developed by one-step hydrothermal method. Because multipathway charge and mass transport, hierarchically structured g-C3N4 nanoribbon-graphene hybrids lead to high ability HER Tafel slope 54 mV decade(-1), low onset overpotential 80 207 approach current 10 mA cm(-2), superior those non-metal materials well-developed metallic reported previously. This work presents advance designing developing highly efficient catalyst evolution.
