Angewandte Chemie, EarlyView.Mesopore geometry programs the working‐state interface of Fe single sites during nitrate electroreduction. Hexagonal channels reorganize interfacial water and accompany the reversible evolution of isolated Fe─O4‐like sites toward Fe─O─Fe‐like motifs, promoting successive hydrogenation toward NH3 with a Faradaic efficiency of 99.1%.

Integrating Catalytic Processes and Modern Electrolyte Concepts into Electrosynthesis
CHIMIA, 2020 Electrosynthesis is frequently presented as an intrinsically sustainable, safe and efficient method. While this is indeed often the case, this assessment cannot be easily generalized, as a number of challenges need to be addressed on the way to more ...

Modulation of Local Environment for Selective Bicarbonate Conversion to Multi‐Carbon Products
Advanced Energy Materials, EarlyView.Highly porous Cu electrode partially coated with an ionomer/carbon composite enables efficient conversion of bicarbonate to multi‐carbon products. By regulating the local reaction microenvironment, this strategy overcomes selectivity and reaction‐rate limitations, achieving Faradaic efficiencies of 43% for ethylene and 60% for total multi‐carbon ...

Angewandte Chemie, EarlyView.High‐loading tin single‐site catalysts (>7.5 wt.% Sn) are synthesized using a nitrogen‐enriched carbon scaffold and mechanochemically assisted pyrolysis to stabilize atomically dispersed Sn. The resulting Sn/N‐C‐M catalyst enables highly selective CO2‐to‐formate conversion (>90% FE across 50–500 mA cm−2) with long‐term durability and operando‐verified ...

AIChE Journal, EarlyView.Abstract Conventional continuous plants use fixed‐capacity equipment, resulting in high capital risk and suboptimal performance under fluctuating demands. To address these, this study proposes an integrated framework for modular process design and supervisory control capable of adapting to demand uncertainty for long‐term economic viability.
