Dynamic‐FLPs Enabled by Orbital Hybridization Tuning: Boosting 100% CO Selectivity for Dilute CO2‐to‐CO Conversion

Carbon Energy, EarlyView.
This study, for the first time, constructs photostructured dynamic frustrated Lewis pairs (DFLPs) via a p‐p orbital hybridization regulation strategy, achieving the 100% reduction of low‐concentration CO₂ to CO and breaking the stability‐activity trade‐off.

Beyond Furnaces: Harnessing In Situ Joule Heating for Efficient C1 Catalysis

Carbon Energy, EarlyView.
Joule‐heated catalysis directly converts electrical energy into localized heat within conductive catalysts, overcoming the heat‐transfer limitations of conventional furnaces. This review summarizes recent advances in C1 molecule conversion, including CO2 methanation, reforming for hydrogen production, and HCHO/CO oxidation, while highlighting ...

(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3

Chemistry – A European Journal, EarlyView.
The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

Chemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Treatment and recycling of spent nuclear fuel

, 2008
Après son passage en réacteur, le combustible nucléaire usé contient encore beaucoup de matières valorisables au plan énergétique (uranium, plutonium), ainsi que des produits de fission et actinides mineurs qui représentent les résidus des réactions nucléaires.
