## Title

- title: Tuning Electronic and Proton Transfer Properties on Amino-Functionalized
    Co-Based MOF for Efficient Photocatalytic Hydrogen Evolution
  title_type: original
  lang: en

## Description

- description: Efficient hydrogen (H2) production through photocatalytic water splitting
    was achieved by using an amino-functionalized azolate/cobalt-based metal–organic
    framework (MOF). While previous reports highlighted the amino group’s role only
    as a substituent group for enabling light absorption of MOFs in the visible region,
    our present study revealed its dual role. The amino substituent not only acts
    as an electron donor to increase the electron availability at the active Co sites
    but also provides hydrogen-hopping sites within the pore channel, facilitating
    proton (H+) diffusion along the framework. This dual functionality significantly
    boosts the performance of this Co-MOF as a hydrogen evolution cocatalyst. When
    combined with fluorescein and triethylamine as the photosensitizer and sacrificial
    agent, respectively, the Co-MOF achieved a remarkable H2 production rate of 27
    mmol g–1 over 4 h. Notably, this performance surpasses those of benchmark platinum
    (Pt) and titanium dioxide (TiO2) cocatalysts.
