Abstract Hybrid lead halides show significant potential in photocatalysis due to their excellent photophysical properties, but the atomically precise modification of organic component achieve synergistic interactions with halide units remains a great challenge. Herein, for first time, we have employed crystal engineering strategy construct class single‐atom‐substituted hybrid electron donor‐acceptor (D‐A) effect. The frameworks consist 1D linear [PbCl] + chains as inorganic building and benzoxadiazole/benzothiadiazole/ benzoselenadiazole‐funtionalized dicarboxylates linkers. covalent bonding between ligands electron−withdrawing groups electron‐rich not only facilitate charge separation, also enhance structural robustness that is critical photocatalysis. D‐A structured serve highly efficient heterogeneous photooxidation catalysts, including aerobic oxidation C(sp 3 )−H bonds, oxidative coupling primary amines, phenylboronic acids selective sulfides are demonstrated 30 examples. Importantly, these reactions able be driven by natural sunlight ambient air afford quantitative yields. Moreover, our photocatalysts successful fix into photocatalytic flow system, which enables flow‐type synthesis high value‐added products on gram scale.

Abstract Metal halide perovskite (MHP)‐based photocatalysts encounter significant stability challenges in water‐containing systems, posing a major obstacle to their application artificial photosynthesis. Herein, an innovative and universal strategy is present create MHP‐based ternary heterojunctions based on self‐templating method. A series of composite catalysts featuring sandwich hollow structures are constructed, with MHPs such as CsPbBr 3 , Cs Bi 2 I 9 Sb Br AgBiBr 6 serving the intermediate layers. The unique structure effectively shields from direct water contact, allowing exhibit exceptional photocatalytic environments for durations exceeding 200 h. Furthermore, design ensures complete contact between reaction substrates both oxidation reduction functional areas. Compared single materials, heterojunction stronger capability improved charge separation efficiency, leading substantial enhancement CO performance. Notably, layer achieves electron consumption rate up 1824 µmol g −1 h reduction, which far superior other reported under similar conditions.

Excessive hole-accumulation-induced photocorrosion is considered a key factor that limits the activity of photoelectrochemical water splitting reaction. In this study, heterogeneous catalyst was prepared by simple impregnation method, i.e., modification different ratios heterometallic oxyhydroxides (FexCo1-xOOH) on in situ photoreduction-treated BiVO4 (Bi-BVO). This work demonstrates for first time adjusting FeCo ratio can greatly enhance separation, transport, and directional control electron-hole pairs, thus inhibiting photocorrosion. The Bi-BVO/Fe0.7Co0.3OOH composite exhibited photocurrent density 0.243 mA cm-2 at 1.23 VRHE (4.5 times pure under 1.5 G AM illumination) sacrificial agent-free Na2SO4 electrolyte. After 20 h continuous illumination, optimized samples showed negligible attenuation (7.2%). strong stability light conditions be attributed to Fe Co acting as hole shuttling mediators, which efficiently match generation rate Bi-BVO transport surface active sites. Furthermore, formation Co-O-V bonds passivation states, immobilize V5+ lattice, further inhibit bimetallic oxyhydroxide strategy provides valuable insights into mitigating offers an optimization approach splitting.
