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.

SPEM at near-ambient pressure: Scanning photoemission microscopy (SPEM) is now able to overcome the “pressure gap” that limits the use of spatially resolved photoemission spectroscopy in the investigation of catalytic systems. In this work for the first time we show the acquisition of photoemission maps and spectra with a spatial resolution of 100 nm on samples exposed to pressures in the 1 mbar range.
- Surface Segregation of Fe in Pt–Fe Alloy Nanoparticles: Its Precedence and Effect on the Ordered-Phase Evolution during Thermal Annealing
Sagar Prabhudev, Dr. Matthieu Bugnet, Dr. Guo-Zhen Zhu, Dr. Christina Bock and Dr. Gianluigi A. Botton

Surface-segregation vs atomic-ordering: By using atomic-resolution imaging and electron energy loss spectroscopy and employing both ex situ and in situ approaches, an ongoing interplay between segregation and ordering during the thermal annealing of Pt—Fe alloy nanoparticles is studied. Findings reveal a surface segregation of Fe that is in contrast to earlier reports suggesting Pt surface segregation.

Deeply DIPEA about… A palladium-catalyzed reductive Heck reaction of aryl iodides to α,β-unsaturated ketones is described using N,N diisopropylethylamine (DIPEA, Hünigs base) as the reductant. A deuterium labeling study shows that the reaction is a bona fide reductive Heck reaction and excludes a Heck reaction-conjugate reduction cascade.
- Methanol Oxidation Reaction on α-Tungsten Carbide Versus Platinum (1 1 1) Surfaces: A DFT Electrochemical Study
Prof. Dr. Cristiana Di Valentin, Diego Fittipaldi and Prof. Dr. Gianfranco Pacchioni

Something MORish: Tungsten carbide basal and prismatic surfaces are compared directly to Pt (1 1 1) as electrocatalyst materials for the methanol oxidation reaction (MOR) in terms of Gibbs free energy profiles along the reaction paths and the required overpotential for the half-cell to produce CO2. The comparative analysis shows that WC basal and prismatic surfaces are promising alternatives to Pt, especially if doped with an excess of electronic charge.
