Key Drivers of Activity and Selectivity in Cu‐Based Catalysts for Methanol Synthesis From CO2: Insights From Atomically Dispersed Promoters

Angewandte Chemie, EarlyView.
Mechanistic studies on model Cu─M/SiO2 catalysts (M = Zn, Ga, and In) reveal that promoters enable a formate spillover pathway from Cu to Mn+ (n = 2 or 3) sites. The promoter's electronic effect on formate bond strengths serves as a quantitative descriptor for activity and selectivity, balancing spillover dynamics with intermediate stabilization to ...

Exclusive Hydroformylation of Terminal Olefins: A Phosphorus‐Free Ruthenium System for the Selective Functionalization of Complex Mixtures

Angewandte Chemie, EarlyView.
Development of a phosphorus‐free Ru/DBU catalyst enabling highly chemo‐ and regioselective hydroformylation of terminal olefins, sparing internal double bonds. Optimization of reaction parameters, ligand effects, and substrate scope including industrial feedstocks was realized.

Microenvironment Engineering as a Design Principle for Suppressing Catalyst Metal Loss

Angewandte Chemie, EarlyView.
Under ionomer‐containing microenvironments, nonporous carbon supports enhance the retention of dissolved platinum ions, whereas porous carbon supports promote pore‐confined redeposition and mitigate net platinum loss. ABSTRACT Stability losses in platinum electrocatalysts arise from dissolution, redeposition, and restructuring processes that are ...

Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx

Angewandte Chemie, EarlyView.
The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.

The Role of Zn–Hf Site Proximity and Oxygen Vacancies for Methanol Formation Over ZnHfOx Catalysts Under CO2 Hydrogenation Conditions

Angewandte Chemie, EarlyView.
ZnHfOx catalysts enable highly selective hydrogenation of CO2 to methanol over a wide range of Zn contents, as the Zn‐VO‐Hf active motif (VO = oxygen vacancy) exists not only in solid solution‐type ZnHfOx for low Zn contents (≤ 35 mol%), but also as HfOx cluster/single atom decorated ZnO surfaces for Zn contents > 95 mol%.
