Abstract Semihydrogenation is a crucial industrial process. Noble metals such as Pd have been extensively studied in semihydrogenation reactions, owing to their unique catalytic activity toward hydrogen activation. However, the overhydrogenation of alkenes alkanes often happens due rather strong adsorption on active phases. Herein, we demonstrate that incorporation phases single‐atom sites perovskite lattices SrTiO 3 can greatly alternate electronic structure and coordination environment facilitate desorption than further hydrogenation. Furthermore, incorporated be well stabilized without sintering by host–guest interaction with during activation H species hydrogenation reactions. As result, (Pd‐SrTiO ) exhibits an excellent time‐independent selectivity (>99.9 %) robust durability for photocatalytic phenylacetylene styrene. This strategy based will broad implications development high‐performance photocatalysts selective

MOF-based heterojunctions can significantly enhance the efficiency of photocatalytic hydrogen production; however, construction efficient remains a formidable challenge. In this study, we successfully developed series Type II by growing TiO2 on Cr-based MOF, thereby regulating generation, separation, and transportation photogenerated charge carriers to improve evolution performance. Among these, 23%TiO2/MIL-101(Cr) photocatalyst exhibited highest production activity, achieving 884.01 μmol g–1 in just 5 h, which is 6.8 6.0 times that pure MIL-101(Cr) TiO2, respectively. Additionally, demonstrated excellent cyclic stability. Tiny particles were proven mainly deposited surface N2 sorption isotherm analyses, transmission electron microscopy (TEM), high-resolution TEM, high-angle annular dark field scanning microscopy, etc. Characterization techniques such as situ XPS confirmed formation TiO2/MIL-101(Cr) heterostructure. Band structure analysis indicates meets thermodynamic requirements for production. Furthermore, transient photocurrent measurements, electrochemical impedance analysis, photoluminescence reveal possesses superior capabilities carrier transport, resulting from kinetic perspective.

Abstract Despite coordination environment of catalytic metal sites has been recognized to be great importance in single‐atom catalysts (SACs), a significant challenge remains the understanding how location‐specific microenvironment higher sphere influences their catalysis. Herein, series Cu‐based SACs, namely Cu 1 /UiO‐66‐X (X=‐NO 2 , ‐H, and ‐NH ), are successfully constructed by anchoring single atoms onto Zr‐oxo clusters metal–organic frameworks (MOFs), i.e., UiO‐66‐X. The ‐X functional groups dangling on MOF linkers could regarded as remote regulate electronic properties atoms. Remarkably, they exhibit differences catalysis toward hydroboration alkynes. activity follows order /UiO‐66‐NO > /UiO‐66 /UiO‐66‐NH under identical reaction conditions, where showcases phenylacetylene conversion 92 %, ~3.5 times efficiency than that .
