Vertical graphene nanowalls with abundant defective edges promote the bonding of metallic precursors for the realization of advanced hybrid nanostructured electrodes.
To accelerate the transition to a green economy based on hydrogen, more efficient and cost-effective electrocatalysts should be adapted. Here, we introduce a bottom-up approach involving chemical vapor deposition, impregnation in solvent containing the Mo precursor and thermal annealing processes to carburize the Mo nanostructures anchored on vertical graphene nanowalls supports (GNWs). This study paves the way for the design of hybrid nanostructures, utilizing nanocatalyst deposition on three-dimensional graphene supports. Such advancements hold great potential for driving the development of sustainable and efficient hydrogen production systems.
