Acceptor‐Doped Cerium Oxides Enabling Metallic Nanocatalyst Exsolution for Hydrogen Production From Ammonia

open access: yesAngewandte Chemie, EarlyView.
Outstanding catalytic results for NH3 decomposition for H2 production were obtained with metallic Ru, Rh, and RuRh nanoparticle‐exsolved CeO2‐based catalysts. Significant lower amounts of available superficial metallic fractions were needed in comparison to conventional Ru‐impregnated materials.

Decouple H2O2 Electrosynthesis From Microenvironmental Decomposition via Atomic Site Density Engineering

open access: yesAngewandte Chemie, EarlyView.
Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...

Reaction Environment Engineering for Selective C3+ Formation in CO2 Electroreduction: Progress and Perspectives

open access: yesAngewandte Chemie, EarlyView.
This work focuses on how to improve the selectivity and activity of electrocatalytic CO2 reduction to C3+ products, by the integration of electrocatalyst and electrolyte co‐design. We summarize key C3+ formation mechanisms and provide a comprehensive reaction network through thermodynamic analysis.

Organocatalytic Enantioselective Addition of Malonates to Cyclic Imines: A Short Total Synthesis of Tetraponerine T‐1

open access: yesAngewandte Chemie, EarlyView.
A stereoselective functionalization method of cyclic imines under mild organocatalytic conditions was developed. Bifunctional cinchona alkaloid catalysts combined with carefully optimized reaction conditions to suppress background reactivity enabled highly enantio‐ and diastereoselective addition reactions of malonates to cyclic imines.

Electrochemically Induced Structural Evolution to Generate Optimized High‐Entropy‐Alloy Electrocatalysts for Ethanol Oxidation

open access: yesAngewandte Chemie, EarlyView.
Electrochemical cycling drives spontaneous facet optimization in high‐entropy Pd@PdPtIrRuRh core‐shell nanocrystals, reshaping simple cubes into severely beveled architectures with balanced {100}/{110}/{111} facets. This dynamic restructuring yields active electrocatalysts that favor complete ethanol oxidation via the C1 pathway, suppress strongly ...
