Abstract Photocatalytic generation of H₂O₂, involving both oxygen reduction and water oxidation without sacrificial agents, necessitates maximized light absorption, suitable band structure, efficient carrier transport. Leveraging the redox capacity this study designs constructs a step‐scheme heterostructured SnO₂/Zn₃In₂S₆ catalyst for H₂O₂ production from seawater under ambient conditions first time. This photocatalyst demonstrates remarkable rate 43.5 µmol g⁻¹ min⁻¹ which can be increased to 80.7 with additional O₂ injection. Extensive in situ ex characterizations, supported by theoretical calculations, reveal transport robust ability, enabling complete photosynthesis at sites S‐scheme heterojunction. Furthermore, it is hypothesized that substituting SnO₂ other semiconductors such as TiO₂, WO₃, BiVO₄ all form results confirm feasibility design. Additionally, recycling further utilization produced. These findings offer new insights into design heterostructure architectures present opportunities agents.

The meticulous design of advanced electrocatalysts and their integration into gas diffusion electrode (GDE) architectures is emerging as a prominent research paradigm in the H2O2 electrosynthesis community.

Here, we elucidate pivotal role mass transfer behavior key species (including reactants products) beyond intrinsic properties electrocatalyst dictating electrode-scale selectivity. This tendency becomes more pronounced high reaction rate (current density) regimes where transport limitations are intensified. By utilizing diffusion-related parameters (DRP) GDEs (i.e., wettability catalyst layer thickness) probe factors, employ both short- long-term electrolysis conjunction with in-situ electrochemical reflection-absorption imaging theoretical calculations to thoroughly investigate impact DRP DRP-controlled local microenvironments on O2 transfer. mechanistic origins diffusion-dependent conversion at scale unveiled accordingly. fundamental insights gained from this study underscore necessity architectural innovations for mainstream hydrophobic can synchronously optimize products, paving way next-generation gas-consuming electroreduction scenarios.
