Summary: The study on a series of palladium(II) complexes with bis(NHC) ligands immobilized on TiO2 surface reveals that these complexes evolve to Pd NPs at the TiO2 surface under reaction conditions, releasing Pd species in the liquid phase. The reactivity is enhanced by the in situ generation of Mott-Schottky heterojunctions, leading to new pathways for the design of heterogenized catalysts in reverse-flow reactors.

Summary: Despite extensive studies on the reaction of Pd intermediates in the Suzuki-Miyaura reaction (SMR), direct evidence supporting the widely accepted assumptions regarding the activity of Pd hydroxo complexes is lacking. This study presents results on the reactivity of Pd-OH and/or Pd-OR-containing complexes in the transmetalation step under ligand-free turnover conditions. The catalytic involvement of specific Pd species was determined under real catalytic conditions by measuring the selectivity of competing reactions.

Summary: This study investigates the catalytic activity of Pd (II) complexes of phosphino-benzaldoxime ligands in Suzuki-Miyaura coupling reactions. The results show that reducing the amount of catalyst leads to an increase in catalytic activity, and it is found that palladium nanoparticles formed in the reaction medium are responsible for this activity. This study contributes to the debate over whether the catalytic activity of phosphine-palladium complexes in SMC reactions results from a homogeneous or heterogeneous pathway.

These Rh/MOFs were demonstrated to be active heterogeneous catalysts for the hydrogenation of unsaturated hydrocarbons at mild reaction conditions, with an activation step required during the initial run of the catalytic process. In situ Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) was utilized to monitor the activation pathway of the catalyst under a H-2 atmosphere.

Summary: In the hydrogenation of acetophenone catalyzed by a new Pd/S-DVB catalyst, a solvent effect was found to impact the reaction efficiency. The solvent's hydrogen-bond-acceptance capacity correlates with the conversion of acetophenone, and binary mixtures of alcohol and water significantly decrease the reaction efficiency due to the microheterogeneity and blocking of the catalyst surface.

Summary: In this study, NiGa alloy particles supported on CeO2, ZrO2, and ZrO2-CeO2 solid solutions were prepared and characterized. The nature of the support was found to have a significant influence on the catalyst's activity and selectivity, with the crystalline structure of ZrO2 having the greatest impact. Pure ZrO2 showed the highest methanol selectivity and CO2 conversion at high Zr:Ce ratios. In equimolar and Ce-rich conditions, basic sites and oxygen vacancies were found to be the key parameters affecting methanol production.

Summary: 1,6-Hexamethylenediamine was successfully synthesized via the reductive amination of 1,6-hexanediol using a Ru/PRL(x)-Al2O3 catalyst. The highly dispersed and anchored Ru species, formed by 1,10-phenanthroline (PRL), played a crucial role in the catalytic reaction. The formation of new acid-base pairs, electron deficient Ru species, and smaller nanoparticles contributed to the improved catalytic performances of the Ru/PRL-Al2O3 catalyst.

Summary: Efficiently addressing the challenges of photocatalytic CO2 reduction to CH3OH is crucial. This study developed Zn-BTC MOF and its composites with CaIn2S4, achieving highly efficient and robust photocatalytic CO2 reduction to CH3OH under ambient conditions, using H2O2 as the hydrogen source. Among the composites, ZMCIS4 demonstrated excellent performance with a CH3OH evolution of 49100 μmol/g.cat and a quantum efficiency of approximately 78.41%. The enhanced performance was attributed to the production of nascent hydrogen atoms (H center dot) through the photo-splitting of H2O2 on the ZMCIS surface.

Summary: In this study, several silica-alumina catalysts modified with Ag were examined for the dehydration of 1,3-butanediol to 1,3-butadiene. Among them, an amorphous silica-alumina catalyst (SAL-3) modified with Ag showed the highest improvement in catalytic activity and stability when operated in H2 flow. The generation of reversible acid sites was found to be the reason behind the enhanced activity and stability of this Ag/SAL-3 catalyst. The effects of various parameters on the catalytic activity of Ag/SAL-3, such as reaction temperature, contact time, Ag content, and carrier gas, were investigated.
