Bimetallic Ni2−xCoxP carbon nanofibers network: Solid-Solution-Alloy nano-architecture as efficient electrocatalysts for water splitting

Ni 2− x Co x P/CNFs ( x = 0, 0.67, 1, 1.33 and 2), where the ultrafine Ni 2− x Co x P nanoparticles are encapsulated in carbon nanofibers, are synthesized using a facile electrospinning method followed by thermal treatment.
