Polyoxometalate as Hydrogen–Electron Hub in Metal–Organic Complex for Electrocatalytic Nitrate Reduction to Ammonia

Advanced Science, EarlyView.
To tackle low electrocatalytic nitrate reduction to ammonia efficiency in neutral media, this work designs chain‐like dinuclear/trinuclear polyoxometalate‐based metal‐organic complexes. Metal clusters provide nitrate adsorption/activation sites, while polyoxometalates (POMs) drive water dissociation to generate active hydrogen (*H) that migrates to ...

Water‐Soluble Metal Phthalocyanines Enable Molecularly Dispersed Heterogeneous Electrochemical CO2 Conversion

Advanced Science, EarlyView.
Water‐soluble metallophthalocyanines self‐assemble onto the surface of carbon black via π–π interactions, creating highly dispersed and electronically coupled MPcTs/CB, which enables selective CO2‐to‐CO conversion in aqueous media with near‐quantitative Faradaic efficiency and remarkable stability. Optimized flow‐cell operation delivers up to 500 mA cm−
