The precise facet modulation of transition metal nitrides (TMNs) has been regarded as an essential issue in boosting electrocatalytic H2 production. Compared to thermal nitridation, the plasma technique serves as a favorable alternative to directly achieve TMNs, but the apparent surface heating effect during plasma treatment inevitably causes the thermally stabilized nitride formation, resulting in...
Prereduction of transition metal oxides is a feasible and efficient strategy to enhance their catalytic activity for hydrogen evolution. Unfortunately, the prereduction via the common H2 annealing method is unstable for nanomaterials during the hydrogen evolution process. Here, using NiMoO4 nanowire arrays as the example, it is demonstrated that carbon plasma (C‐plasma) treatment can greatly enhance...
Developing transition metal nitrides with unique nanomorphology is important for many energy storage and conversion processes. Here, a facile and novel one‐step approach of growing 3D hierarchical nickel nitride (hNi3N) on Ni foam via nitrogen plasma is reported. Different from most conventional chemical synthesis, the hNi3N is obtained in much shorter growth duration (≤15 min) without any hazardous...
