A Thermally Robust Luminescent Antimony Halide for Real‐Time Detection of Volatile Iodine at Elevated Temperatures

EcoEnergy, EarlyView.
Zero‐dimensional antimony halides drive efficient iodine capture through electron transfer and display rapid fluorescence quenching at 75°C (348 K), establishing the first luminescent sensor for real‐time I2 detection at elevated temperatures. ABSTRACT Real‐time monitoring of volatile molecular iodine (I2), a hazardous radioactive byproduct of nuclear ...

Selective Hydrogenation of Formamide to Methanol Over Supported Platinum Catalysts. [PDF]

Angew Chem Int Ed Engl
Amine–CO2 adducts can be hydrogenated to formamides and subsequently to methanol under mild conditions (<150°C), establishing an integrated CO2 capture‐and‐conversion route in a heterogeneous system that directly links amine sorbent cycling with methanol synthesis.

Water‐Activated Proton Transfer Mediated by Subnanoscale CeO2‐Cu2O Interfaces for Near‐Unity CH4 Selectivity in Photothermal CO2 Reduction

EcoEnergy, EarlyView.
Subnanoscale CeO2‐Cu2O particles can efficiently catalyze the hydrogenation of the key intermediate *CO to CH4 at an impressive rate of 2818 μmol g−1 h−1 in photothermal CO2 reduction. ABSTRACT Water‐mediated photothermal CO2 reduction to CH4 is promising for renewable energy storage and carbon neutrality, but its selectivity and efficiency are limited

Ag‐Regulated Cu‐Sites on a Conductive Cu‐Metal‐Organic Framework for Enhanced CO2 Electroreduction to CH4

EcoEnergy, EarlyView.
We present a strategy of integrating Ag NPs with a 2D Cu3(HHTP)2 framework to boost selective CO2 electroreduction. The optimal composite achieves 65.1% FECH4 ${\text{FE}}_{{\text{CH}}_{4}}$ at 240 mA cm−2. Synergistic effects enhance CO2 adsorption, facilitate electron transfer, and selectively stabilize key reaction intermediates, steering the ...

Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.
