CVD-grown NiO-carbon nanofiber decorated rGO hybrids for high-performance electrochemical hydrogen storage: role of hierarchical porous structures.

The development of sustainable materials for green energy storage systems has accelerated due to the growing demand for energy worldwide and environmental concerns. Because of their large surface area, electrical conductivity, and adjustable structure, mesoporous graphitic carbon-based materials show the most promise for electrochemical hydrogen storage (EHS). The electrochemical performance of these materials is further improved by integrating them with transition metal oxides.
