Hybrid Photocatalytic Porphyrin‐Functionalized UiO‐66/BiVO₄ for Enhanced CO₂ Reduction Using Photosystem II

Harnessing abundant solar energy for sustainable fuel production offers one of the most encouraging strategies to mitigate CO 2 emissions. The discovery of novel and efficient photocatalysts to enhance photocatalytic CO 2 reduction is important for converting solar energy to fuel. Porphyrin‐functionalized UiO‐66 on a BiVO 4 semiconductor is introduced to convert CO 2 via photoreactions. Here, the solar‐driven production of carbonaceous feedstocks is reported using a novel photocatalytic material S‐scheme UiO‐66‐TCPP‐BiVO 4 heterojunction coupled with the photosystem II (PSII) in a microalgae. Coupling PSII with synthetic catalysts improves the efficiency of light‐harvesting and the CO 2 reduction reaction (CO 2 RR). Electrochemical impedance spectroscopy, transient photocurrent response, photoluminescence lifetime, X‐ray photoelectron spectrometer, transmission electron microscope (TEM), X‐ray diffraction (XRD), and electron spin resonance measurements are conducted to determine the complex structural and electronic properties and the photocatalytic performance. In situ Fourier‐transform infrared spectra provide the CO 2 RR processes, revealing the mechanism by detailing intermediate formation and energy pathways.
