## Title

    and uniform dispersion of Pt-group single atoms

## Description

- description: Atomically dispersed Pt-group metals are promising as nanocatalysts
    because of their unique geometric structures and ultrahigh atomic utilization.
    However, loading isolated Pt-group metals in single-atom alloys (SAAs) with distinctive
    bimetallic sites is challenging. In this study, we present amorphous mesoporous
    Ni boride (Ni-B) as an ideal substrate to uniformly disperse Pt atoms with tunable
    loadings (1.7 to 12.2 wt %). The effect of the morphology, composition, and crystal
    phase of the Ni-B host on the growth and dispersion of Pt atoms is discussed.
    The resulting amorphous Pt-Ni-B mesoporous nanospheres exhibit superior electrocatalytic
    H2 evolution performance in acidic media. This strategy holds the potential to
    synthesize a diverse library of mesoporous amorphous Pt-group SAAs, by leveraging
    functional amorphous nanostructured 3d transition-metal borides as substrates,
    thereby proposing a comprehensive strategy to control atomically dispersed Pt-group
    metals.
