Ni4Mo nanoparticles embedded in N-doped carbon nanotubes growing on Ni4Mo/MoO2 micropillars for durable hydrogen evolution

N-doped carbon nanotubes embedding Ni4Mo particles at the tips growing on Ni4Mo/MoO2 micropillars were achieved as a highly efficient HER electrocatalyst. This well-designed NCNTs@Ni4Mo/MoO2 heterostructure catalyst exhibits excellent durability and high activity toward the hydrogen evolution reaction.
