## Description

- description: Photocatalytic oxygen reduction to H2O2 is a promising sustainable
    solar fuel production pathway. Photocatalysts with heterostructure interfaces
    can suppress charge carrier recombination and endow photo-generated electrons
    and holes with improved redox potentials. This study develops a heterostructured
    two-dimensional (2D) MoS2/MnIn2S4 photocatalyst for photocatalytic H2O2 production.
    The photocatalyst with an optimal loading of MnIn2S4 on 2D MoS2 nanosheets demonstrates
    the maximum H2O2 production rate of 606.7 µmol g⁻¹ h⁻¹, approximately 4.2 and
    5 times higher than pristine 2D MoS2 and MnIn2S4, respectively. The synergistic
    interaction between 2D MoS2 nanosheets and MnIn2S4 results in enhanced charge
    separation, optical absorption, stability, and recyclability. Reaction pathway
    studies reveal that H2O2 production is through a sequential single-electron O2
    reduction reaction by accumulated photo-generated electrons on the conduction
    band of the 2D MoS2/MnIn2S4 heterostructure. This work presents a noble-metal-free
    photocatalyst responsive to visible light for solar H2O2 generation.
