    Hydrogen (H) production and environmental cleanup, including pollutant breakdown, nano‐plastic removal, and CO reduction, are crucial for achieving environmental sustainability. Piezo‐photocatalysis has appeared in an optimistic approach to address environmental pollution and the escalating energy crisis. Although several reviews on H production and environmental cleanup using piezo‐catalytic technologies have been recently published, there is no review specifically focused on the literature related to dual‐functional piezo‐photocatalytic systems. This research aims to fill that gap as the field continues to grow rapidly. This study reviews dual‐function piezo‐photocatalytic systems, which can be easily fabricated to enhance the effective uncoupling and transfer of photoproduced holes and electrons for H production and environmental cleanup. First, piezoelectric materials, such as metal oxides (e.g., TiO, ZnO, BaTiO), 2D materials (e.g., MoS, MXenes, graphene‐based materials), perovskite materials, and composite/heterostructure materials, are introduced. Second, this work also explores various modification methods that enhance piezo‐photocatalytic efficiency, highlighting the remarkable properties of dual‐function systems designed for sustainable H production and environmental cleanup. Additionally, this work provides insight into the underlying mechanisms of piezo‐photocatalytic activity and suggests new pathways toward high‐performance piezo‐photocatalysts. Finally, this research discusses future directions for piezoelectric materials in environmental applications and sustainable H production.

    Harnessing abundant solar energy for sustainable fuel production offers one of the most encouraging strategies to mitigate CO2 emissions. The discovery of novel and efficient photocatalysts to enhance photocatalytic CO2 reduction is important for converting solar energy to fuel. Porphyrin‐functionalized UiO‐66 on a BiVO4 semiconductor is introduced to convert CO2 via photoreactions. Here, the solar‐driven production of carbonaceous feedstocks is reported using a novel photocatalytic material S‐scheme UiO‐66‐TCPP‐BiVO4 heterojunction coupled with the photosystem II (PSII) in a microalgae. Coupling PSII with synthetic catalysts improves the efficiency of light‐harvesting and the CO2 reduction reaction (CO2RR). 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 CO2RR processes, revealing the mechanism by detailing intermediate formation and energy pathways.
