Low-Pt-content hierarchical selenide nanoarrays for accelerated hydrogen evolution through optimized hydrogen adsorption.
The development of electrocatalysts that combine low noble-metal loading with high catalytic activity is an important strategy for improving the efficiency of hydrogen evolution reaction (HER). Herein, a hierarchical PtSe2/CoSe2/MoSe2/NiSe nanoneedle array catalyst, denoted as PtCoMoNi-Se, was fabricated to exploit the...
