The design of photocatalysts with hierarchical pore sizes is an effective method to improve mass transport, enhance light absorption, and increase specific surface area. Moreover, the construction a heterojunction at interface two semiconductor suitable band positions plays crucial role in separating transporting charge carriers. Herein, ZIF-8 urea are used as precursors prepare hierarchically porous ZnO/g-C3N4 S-scheme through two-step calcination method. This photocatalyst shows high activity toward photocatalytic H2O2 production, which 3.4 5.0 times higher than that pure g-C3N4 ZnO, respectively. mechanism transfer separation within studied by Kelvin probe, situ irradiated X-ray photoelectron spectroscopy (ISI-XPS), electron paramagnetic resonance (EPR). research provides idea designing pores efficient hydrogen peroxide production.
