“…These excited electrons are then transferred to the interior of microbial cells through cytochromes on the cell surface and extracellular proteins. This process accelerates microbial cell metabolism and energy conversion (Liu et al, 2023a;Lv et al, 2024). Meanwhile, excess h + is oxidized by the electron donor to maintain the continuous operation of the systems (common electron donors are illustrated in Figure 5 (Lee et al, 2018)).…”

“…Experimental findings show that the Escherichia coli-TiO2-x biohybrid system exhibits significantly higher hydrogen production than the Escherichia coli-TiO2 and pure Escherichia coli systems. In three h, the Escherichia coli-TiO2-x biohybrid system generated 1.25 mmol of hydrogen, 3.31 times more than the pure Escherichia coli system (Lv et al, 2024). To enhance the selectivity of synthesized metabolites in SAPS, Ye et al (2022b) incorporated NiCu alloy at the interface of Methanosarcina barkeri and CdS nanoparticles (Fig.…”

Creatively integrating synthetic materials (semiconductors and electrodes) and microorganisms, the semi-artificial photosynthetic system (SAPS) couples the advantages of natural photosystems (high catalytic reaction selectivity) and artificial photosystems (excellent light-harvesting performance). This combination effectively overcomes the shortcomings of poor selectivity in artificial photosystems, bringing new opportunities for developing photosynthetic systems. It also provides a promising strategy for addressing the current energy crisis and environmental pollution. The design and selection of synthetic materials play a crucial role in this system, aiming to achieve efficient photon capture and electron transfer. This review begins by exploring the fundamental principles of SAPS, emphasizing the integration of materials and microorganisms and the factors that influence their interactions. It provides a critical analysis of the diverse compositional arrangements and systematically elucidates the foundational research methodologies employed in the investigation of SAPS. Grounded in their distinctive redox characteristics, it comprehensively surveys their recent applications in environmental remediation and sustainable energy production over the past years. Finally, reflections on future research are proposed, beginning with the challenges that limit the application of SAPS. Building on previous studies, the present review identifies the factors that limit SAPS and suggests potential avenues for future research. Additionally, this review delves into the environmental and economic policies and practical implications. In conclusion, by critically assessing the existing research landscape, delineating challenges, and charting future research directions, the present review aims to provide valuable insights for researchers and practitioners, guiding efforts toward advancing SAPS for enhanced environmental sustainability and economic feasibility.
