## Description

- description: Amorphous metal–selenium (M–Se) alloys hold promise for applications
    such as catalysis, electronics, and surface-enhanced Raman spectroscopy (SERS)
    sensing due to their surface reactivity, isotropic properties, and tunable bandgap.
    However, controlling the synthesis of nanostructured noble-metal-based M–Se materials
    is difficult, as the strong metallic bonding and low chemical reactivity of noble
    metals hinder homogeneous selenization. Here we show a one-step micellar self-assembly
    reduction method to produce amorphous semiconducting Rh–Se mesoporous nanospheres
    (a-Rh–Se MNs). We systematically investigate how composition, surface curvature,
    and crystallinity affect SERS performance. a-Rh–Se MNs with low curvature and
    high amorphization achieve enhanced sensitivity toward typically non-adsorbing,
    low-polarizability analytes, including hexachlorobenzene, anthracene, and polytetrafluoroethylene
    microplastics (even in wastewater). Combined experimental and theoretical analyses
    reveal that co-modulating curvature and amorphization tunes key electronic descriptors
    (e.g., d-band center and work function), thereby promoting resonant charge transfer.
    This finding overturns the conventional paradigm that prioritizes high-surface-area
    substrates. Our work establishes mesostructured a-Rh–Se for SERS applications
    and provides insights into M–Se surface chemistry for designing advanced SERS
    materials.
