“…[1] The efficiency of photocatalysis is generally determined by three factors, including surface reaction, charge transfer/separation, and light absorption. [2] Polymeric carbon nitride (PCN), an organic semiconductor material composed of C and N elements, which has attracted significant attention in photocatalytic applications owning to its excellent properties, including the easily available raw materials, suitable bandgap, and stable physicochemical properties. [3] The bandgap of PCN with tri-triazine structure is nearly 2.7 eV, and the conduction band (CB) minimum and valence band (VB) maximum are about À 1.1 eV and + 1.6 eV (vs. NHE, pH = 0), respectively.…”

S‐scheme heterojunction has emerging as a new star in the field of photocatalysis, attributing to its superior separation of photogenerated charge carriers and strong redox abilities. The general designing criteria and several types of S‐scheme heterojunction were provided. Advanced characterization techniques, including Kelvin probe force microscopy, electron paramagnetic resonance spectroscopy, and in‐situ irradiated X‐ray photoelectron spectroscopy, were presented for disclosing the transfer mechanism in S‐scheme heterojunctions. The recent innovations in the application of photocatalytic oxygen reduction reaction in S‐scheme heterojunction based polymeric carbon nitride photocatalyst were discussed. To conclude, this concept highlights the role of S‐scheme heterojunction in photocatalysis and gives future perspectives on their further applications.

“…In practice, photocatalysts could reduce CO 2 to produce fuel, [2] decompose water to produce H 2 , degrade pollutants in the water cycle system, fix nitrogen to produce NH 3 , etc. However, the efficiency of photocatalyst is limited by the absorption property, the separation efficiency for carriers, and the catalytic efficiency, [3,4] requiring a suitable structure to participate in the redox reaction. To meet the conditions for redox reactions, photocatalysts should have the proper conduction band (CB) and valence band (VB) positions, a suitable bandgap to absorb more sunlight, a strong ability to separate the electron-hole pair, and sufficient active sites to promote reactions.…”

“…Even so, the photocatalysts performance of the Bi-based materials so far couldn't meet industrial requirements. [3] From the microscopic view, carrier recombination is faster than carrier transport, reducing the photocatalytic activity. And most current Bi-based semiconductors still suffer from severe charge recombination.…”

Bi‐based nanomaterials have unique physicochemical and structural properties, allowing them to respond to visible light effectively. The Bi‐based semiconductors can be used for degradation of pollutants, reduction of CO2, nitrogen fixation, and decomposition of water, having the strong potential to address environmental pollution and energy shortages. However, the large‐scale application is still limited by the separation and transfer of electron–hole pairs. Herein this review article, carrier dynamics are studied from three perspectives, including structural modulation, atomic conformational reorganization, and surface modification. The relevant mechanisms of different strategies are mainly highlighted, the variations of carrier motion or lifetime are explored, and the progress in practical studies is elucidated. The structural modulation strategy is first introduced, including different dimensional structures and heterogeneous junctions. Further, the atomic conformational reorganization strategy is presented, including Bi‐rich strategies, doping, and vacancy defects. Additionally, the surface modification strategy is outlined, including facet engineering, loading of semiconductor cocatalysts, precious metals, or single atoms. Finally, these strategies are summarized for regulating carrier dynamics and the outlook with the main research trend, providing more inspiration for designing desirable Bi‐based semiconductors.

Heterogeneous photocatalysts have garnered extensive attention as a sustainable way for environmental remediation and energy storage process. Water splitting, solar energy conversion, and pollutant degradation are examples of nowadays applications where semiconductor-based photocatalysts represent a potentially disruptive technology. The exploitation of solar radiation for photocatalysis could generate a strong impact by decreasing the energy demand and simultaneously mitigating the impact of anthropogenic pollutants. However, most of the actual photocatalysts work only on energy radiation in the Near-UV region (<400 nm), and the studies and development of new photocatalysts with high efficiency in the visible range of the spectrum are required. In this regard, hybrid organic/inorganic photocatalysts have emerged as highly potential materials to drastically improve visible photocatalytic efficiency. In this review, we will analyze the state-of-art and the developments of hybrid photocatalysts for energy storage and energy conversion process as well as their application in pollutant degradation and water treatments.
