Coordination number engineering of Zn single-atom sites for enhanced transfer hydrogenation performance

Enhancing the efficiency of benzylamine oxidative coupling over N-doped porous carbon-supported CeO2 and ZrO2 nanoparticles

“…The choice of solvent also played a critical role in the heterogeneous gas–liquid–solid catalysis reactions. 55–57 Various solvents such as DMF, p -xylene, n -decane, and dodecane were used to investigate their effects on the reaction (Entries 3 to 10). It was found that n -decane, as a solvent, resulted in 97.1% substrate conversion with 100% desired imine selectivity (entry 3).…”

“…Metal–organic frameworks (MOFs) are ideal sacrificial precursors that can be used to construct a diverse range of structurally stable functional materials. 43–62 In this particular study, a bimetallic Ce/Zr MOF ( i.e. , CeZr-NH 2 -MOF) was synthesized via a liquid phase method by introducing a Ce source into the NH 2 -UiO-66 synthesis liquid.…”

Synthesis of an MXene supported Co nanoparticle catalyst for efficient catalytic transfer hydrogenation of nitro compounds with formic acid

“…Pyrolysis of MOFs leads to the formation of carbon-based composites, which exhibit a uniform distribution of metal active sites throughout their porous carbon network, along with large specific surface areas. 19–24 By precisely controlling the annealing conditions, it is possible to design and synthesize multifunctional catalysts with specific properties. For instance, alkaline trifunctionality was observed in Co/Cu nanoparticles embedded in N-doped carbon derived from CoCu-MOFs.…”

Regulating the coordination microenvironment of zinc single-atom catalysts to enhance intramolecular hydroamination performance

“…28,29 This microenvironment encompasses various factors, including the number and type of coordinating atoms, and the doping position, which range from first to higher coordination shells. 24–36 These factors significantly impact the electronic properties and geometric structures of metal centers, thus determining the intrinsic catalytic activity and selectivity of SACs. For example, Wang et al reported an oxide compounding strategy that yielded Cu SACs with a lower coordination number in a Cu–N 2 structure, resulting in effective semi-hydrogenation of alkynes.…”
