Abstract ：
Engineering advanced S-scheme heterojunction photocatalysts represents a prospective strategy for efficient antibiotic-contaminated wastewater decontamination. However, the practical realization of such systems is hindered by difficulties in achieving seamless interfacial integration and precise control over charge-carrier dynamics. Herein, we proposed a shell-core 0D/2D Mn0.5 Cd0.5 S/C3 N5 S-scheme heterojunction with compact interfacial contact, synthesized by in-situ solvothermal growth of Mn0.5 Cd0.5 S nanodots on C3 N5 nanosheets. This optimized Mn0.5 Cd0.5 S/C3 N5 heterojunction performs extraordinary catalytic performance and enables approximately 1.3- and 3.2-fold tetracycline abatement rate greater than that for Mn0.5 Cd0.5 S and C3 N5 , respectively, which arises from the synergy of efficient spatial photo-carrier separation and well preserved great redox capacity of the heterojunction enabled by the S-scheme mechanism. Mechanistic validation was achieved through systematic characterizations and computational analyses. This study advances the rational design of shell-core S-scheme heterojunctions for photocatalytic antibiotic wastewater treatment.

Abstract ：
The photocatalytic activity of a photocatalyst is significantly influenced by its microstructure. Therefore, it is crucial to understand and characterize the microstructure. Transmission electron microscopy (TEM) has been an indispensable tool that provides direct visualization of the microstructure at the atomic level. Despite numerous reviews on photocatalytic processes, there has been a lack of comprehensive summaries that focus on the critical role of TEM in photocatalytic applications. This review aims to fill this gap by highlighting the significant contributions of TEM techniques in understanding key photocatalytic processes, including light absorption, charge separation and transfer, and surface reaction. In addition, this review discusses in-situ TEM techniques for observing photocatalytic reactions and explores the challenges and future perspectives related to the application of TEM in photocatalysis. © 2025

Abstract ：
The construction of S-scheme heterojunction photocatalysts has emerged as a promising strategy to address the urgent need for efficient antibiotic wastewater remediation. However, persistent challenges in achieving interfacial intimacy and precise charge transfer regulation between semiconductors have hindered their practical implementation. In this work, we engineered a hierarchical Cd0.5Zn0.5S/BiOBr S-scheme heterojunction via a controlled solvothermal synthesis, where BiOBr microspheres serve as the core, and Cd0.5Zn0.5S nanoparticles form a conformal shell. This architecture ensures maximal interfacial contact and directional charge dynamics, critical for optimizing photocatalytic efficiency. The optimized heterojunction exhibits superior catalytic performance, achieving tetracycline (TC) degradation rate constants 3.3-and 1.6-fold greater than pristine BiOBr and Cd0.5Zn0.5S, respectively. This enhancement stems from the synergistic interplay of efficient charge separation and preserved redox capacities inherent to the S-scheme mechanism. Furthermore, the TC degradation process and mechanism were elucidated. This study provides a new perspective on developing defective Sscheme heterojunctions for antibiotic wastewater purification with high performance.

Abstract ：
Devising robust S-scheme photocatalysts is of central importance for achieving high-efficient micropollutant decontamination. However, the conscious optimization of S-scheme system with high performance remains a prime challenge. Herein, carbon quantum dots (CDs) and Mn 0.5 Cd 0.5 S (MCS) are mounted on BiOBr (BOB) microspheres, establishing an advanced S-scheme heterojunction with interfacial Bi-S bond. The interfacial Bi-S bonds function as superb channels at atomic-scale to abate the energy barrier for S-scheme charge transportation. Meanwhile, CDs serve as electron collectors to preserve highly reductive electrons from MCS, further augmenting the spatial separation of photo-carriers. Therefore, the optimized CDs/MCS/BOB (MBC) heterojunction manifests significantly strengthened tetracycline hydrochloride (TC) destruction activity and its reaction rate constant is approximately 3.1, 2.2, 2.1, and 1.5 folds that than that of MCS, BOB, BOB/CDs and MCS/BOB. In addition, MBC exhibits high stability and significant resistance to environmental interferences. The toxicology evaluation confirms the effective abatement of toxicity of TC after treatment. This achievement demonstrates the benefits of CDs-optimized S-scheme photosystems with chemical bonds for photocatalytic water decontamination.

Abstract ：
To realize the rapid separation of photogenerated carriers in photocatalytic reactions, large-sized porous carbon nanosheets with Pt dots were utilized as cocatalysts and coupled with TiO2 particles to construct photocatalytic systems. The optimized photocatalytic H-2 yield is similar to 108 times higher than that of TiO2, fully demonstrating the important role of large-sized porous carbon nanosheets with Pt dots for fast charge separation. The shift of the main peak in high-resolution X-ray photoelectron spectroscopies (XPS) verifies the electron transfer from TiO2 to porous carbon nanosheets. The dense distribution of photo-induced Pt deposition on porous carbon nanosheets confirms that active centers for H-2 evolution are mainly located on porous carbon nanosheets. Our work here provides the practicability of constructing large-sized conductive materials as cocatalysts for fast charge separation in photocatalytic reactions.

Abstract ：
Metal halide perovskites with broad optical absorption and long carrier lifetime are considered as ideal photocatalysts. However, their poor stability in water greatly impedes their application in photocatalytic H-2 evolution because they lose their crystalline structure in water. Herein, we proclaim a new class of photocatalysts: all-inorganic Cs-Cu-Cl perovskite quantum dots (QDs). It exhibits a high photocatalytic hydrogen production rate of similar to 3.1 mmol/g/h without any cocatalyst under AM 1.5-G solar irradiation (100 mW/cm(2)). Especially, it remains the high activity for up to 330 h without apparent deterioration of the hydrogen production rate. Density functional theory (DFT) calculations reveal that the Cu site works as the electron and proton absorption sites as the H-2 production active center. To our best knowledge, there is no report of metal halide perovskites as water-stable photocatalysts. This work opens an innovative way for guiding the exploration of metal halide perovskites photocatalysts for stable photocatalytic H-2 evolution.

Abstract ：
The construction of photocatalytic systems with contact interfaces is one of the crucial steps toward the efficient charge separation in photocatalytic reactions. Here, in-situ growth method was utilized to simultaneously obtain ultrathin CuO and TiO2 nanosheets with contact interfaces. The H2 yield of the optimized photocatalyst is - 19.8 mmol/g, - 100 times higher than that of TiO2. In contrast, the samples prepared by physical mixing method only show an H2 yield of - 3.2 mmol/g, fully demonstrating the highly efficient charge separation in in-situ prepared samples. In-situ X-ray photoelectron spectroscopy (XPS) demonstrates the reversible variation of metal valence states and their band-edge shift. This work delivers a new perspective to observe the real-time behavior of metal valances in photocatalysts under light irradiation, which facilities to have a deep understanding of photocatalytic reactions.

Abstract ：
Thedesign of photocatalysts plays a central role in determiningthe photocatalytic H-2 yield. Here, we used a design strategythat is different from conventional methods to prepare our photocatalyticsystems. Large porous carbon aerogels (CA) with rich surface areaswere used to receive photogenerated electrons. TiO2 quantumdots were used as photocatalysts and anchored on large porous CAsto form CA@TiO2 systems. The H-2 yield of theoptimized CA@TiO2 composite is & SIM;2.1 mmol/g, & SIM;11times higher than that of pure TiO2 quantum dots. High-resolutionX-ray photoelectron spectroscopy and high-angle annular dark-fieldscanning transmission electron microscopy demonstrate that the photogeneratedelectrons can be easily transferred from TiO2 quantum dotsto porous CAs. Thus, efficient charge separation can be realized forthe succeeding highly efficient H-2 evolution. Our resultshere provide a different way from conventional methods to design photocatalyticsystems with high H-2 yield.

Abstract ：
Efficient charge separation is one of the critical issues for the design of photocatalytic systems. The physical mixing of photocatalysts and cocatalysts to prepare photocatalytic systems usually leads to a high interfacial resistance, which is not beneficial to efficient charge separation. Here, we report the in situ construction of photocatalytic systems by directly growing CdS nanosheets on porous carbon aerogels (CA) to obtain photocatalytic systems with compact interfacial contact. The photocatalytic H-2 yield of the optimized CdS@CA composite is similar to 27.3 mmol/g, obviously higher than that of CdS nanosheets (similar to 11.4 mmol/g). Electrochemical and spectroscopic methods demonstrate that the incorporation of carbon aerogels with CdS nanosheets can efficiently inhibit the recombination of photo-generated electrons and holes, thus achieving highly improved photocatalytic H-2 production.

Abstract ：
Small-sized particles are usually used as cocatalysts and anchored onto a large-sized photocatalyst for fast charge separation. However, the current problem for the design of photocatalysts is that a high loading of small-sized particles leads to full coverage of photocatalysts, resulting in the decrease of hydrogen production. Here, we propose a different way to construct photocatalytic systems. Large-scale carbon nanotubes with doped nitrogen (N-CNTs) are used to couple with TiO2 quantum dots. The H-2 yield for our optimized photocatalytic system is similar to 146 mmol/g. With further considering the light-induced thermal effect, the H-2 yield reaches up to similar to 320.6 mmol/g. Electrochemical and spectroscopic data show that large-sized N-CNTs can offer abundant active sites to realize the rapid carrier separation for tremendously improved hydrogen production.
