Tailoring the Coordination Environment of Single‐Atom Catalysts for Enhanced Electrochemical CO2‐to‐CO Conversion Efficiency

Carbon Energy, EarlyView.
CO‐N3 and CO‐N4 are delicately prepared to study the role of coordination number on the impact of eCO2RR. The Co site in asymmetric Co‐N3 configuration displays a downshifted d‐band center, facilitating the CO2 activation and the intermediate *COOH formation and the CO2‐to‐CO conversion performance.

Strategies to Enhance Ionic Conductivity of Na3Zr2Si2O12 Solid Electrolyte for Advanced Solid‐State Sodium Batteries

Carbon Energy, EarlyView.
This review presents a comprehensive summary and discussion of some optimization strategies for enhancing room‐temperature ionic conductivity of Na3Zr2Si2PO12 (NZSP) solid electrolyte for solid‐state sodium batteries, including foreign‐ion doping or substitution, sintering behavior modulation, and regulation of chemical composition based on precursors.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
