Summary: The selective hydrogenation of alpha,beta-unsaturated aldehyde to unsaturated alcohol is a significant transformation. In this study, iridium nanoclusters confined within hollow MIL-101(Fe) exhibited high reaction activity and selectivity for cinnamaldehyde hydrogenation. The hollow structure of MIL-101(Fe) facilitated fast reactant transport and improved catalyst recyclability. Furthermore, the interactions between Ir nanoclusters and MIL-101(Fe) as well as the Lewis acid sites in MIL-101(Fe) contributed to the high selectivity of the desired product.

Summary: In this study, a recyclable catalyst, Cu-doped carbon nitride (Cu-CN), was developed as a Cu-photo dual catalytic system. The heterogeneous CN-Cu catalyst can be used for direct alpha-alkynylation of tertiary amines using air as an oxidant, resulting in high yields of diverse propargylamines. The endogenous proximity and synergistic effect between Cu and the photocatalytic center in CN-Cu significantly enhance the Cu-photo dual catalytic activity, improving reaction efficiency and selectivity. Remarkably, this heterogeneous catalyst exhibits high chemical stability and can be recycled at least five times without loss of activity.

Summary: A novel photo-Fenton catalyst FGN with dual Z-scheme heterojunction was successfully prepared and it showed excellent degradation performance towards tetracycline. The optimized preparation conditions and characterization analyses confirmed the successful synthesis of FGN. The experimental results demonstrated that FGN had better light absorption ability, higher separation efficiency of photoelectrons and holes, larger specific surface area, and higher pore capacity compared to other catalysts. The effects of experimental conditions on the degradation performance were investigated and three degradation pathways of tetracycline were proposed. The structural stability and catalytic active sites of FGN were explored by comparing the XRD and XPS spectra. Additionally, the mechanism of the dual Z-scheme heterojunction was proved through various experimental methods.

Summary: A novel heterogeneous catalyst, MoS2/MIL-53(Fe, Cu) (MMFC), was prepared by hydrothermal method and applied in a heterogeneous electro-Fenton system for lomefloxacin degradation. The MMFC system achieved a higher removal efficiency of 93.5% in 60 minutes compared to the MIL-53(Fe, Cu) system. The good catalytic activity was attributed to the effective active sites of the catalyst and the conversion of Fe(II)/Fe(III) and Cu(I)/Cu(II) promoted by Mo(IV) in MoS2.

Summary: Herein, a novel anionic hydrogen-bonded organic framework (HOF-IPCE-1Pd) based on a new complex of palladium(ii) with meso-tetrakis(4-(phosphonatophenyl))porphyrin is reported. The framework shows high crystallinity, simple synthetic procedure, and is easily regenerated. The directed structural transformation of the framework and the absorption of ammonia and water molecules led to the formation of a more hydrolytically stable structure (HOF-IPCE-1Pd-NH3) with a proton conductivity of 1.27 x 10(-3) S cm(-1) at 85 degrees C and 85% RH, which is one of the highest among all known porphyrin-based HOFs. It is noteworthy that the reversible absorbance of water/ammonia molecules preserves the crystal structure of HOF-IPCE-1Pd-NH3.

Summary: This study investigated a novel kinetic model for the adsorption and photocatalytic degradation of methyl orange using commercial ZnO and reduced ZnO photocatalysts. The results provided new insights into the interaction of catalysts with molecules of different charges and compared with a previous study on methylene blue. The presence of oxygen vacancies in ZnO and their effects on adsorption and photocatalytic degradation were analyzed, and the photocatalytic degradation rate of reduced ZnO was found to increase significantly.
