- Titanium Dioxide Reinforced Metal–Organic Framework Pd Catalysts: Activity and Reusability Enhancement in Alcohol Dehydrogenation Reactions and Improved Photocatalytic Performance

Catalysis on the inside! The controlled incorporation of nanoscale Pd and TiO2 inside MIL-101 (Cr) by means of sublimation is reported. The resulting Pd/TiO2@MIL-101 composite materials are efficient catalysts in hydrogenation and dehydrogenation reactions. In addition, an enhanced photocatalytic activity is observed.

Helpful hydrazines: With the aid of an azo directing group, the palladium-catalyzed ortho-sp2 CH bond activation of azoarenes with hydrazines has been explored. The catalyst reacts with azobenzene to form a palladacyclic intermediate, which reacts with a phenyl radical generated from phenylhydrazine produce a PdIV or PdIII intermediate. This undergoes reductive elimination to give the ortho-arylated products and regenerate the catalyst. This reaction provides a novel access to ortho-aryl azoarenes under mild conditions in high yield.
- Probing the Size and Shape Effects of Cubic- and Spherical-Shaped Palladium Nanoparticles in the Electrooxidation of Formic Acid

DRIFTing away: Various structures of adsorbed formate species on a Pd cubic nanoparticle surface are identified by diffuse reflectance infrared Fourier transform spectroscopy analysis. Their coverage and adsorption strength can affect the activity of the electrooxidation of formic acid. Pd(1 0 0) cubes are able to stabilize two bridge formate species and thus show higher electrooxidation activity than Pd spheres at comparable sizes.

Opposing charges, working together: Bifunctional Lewis acidic/basic Pdδ+Ruδ−(1:1) solid-solution nanoparticles disclose a remarkable catalytic efficiency in the Suzuki–Miyaura reaction at very low Pd loading and short reaction time in air. It reveals enhanced reactivity by the electron-withdrawing groups on arylboronic acids, resulting negatively charged aromatic ring in the transition state, which is a clear controversy to the conventional Pd catalysis.
