Summary: Improving the kinetics of solid-state sulfide conversion can enhance the sulfur utilization in metal-sulfur batteries. This study focuses on potassium-sulfur batteries and reports for the first time the reducing overpotential of solid-state sulfide conversion using meta-stable S-3(2-) intermediates on transition metal single-atom sulfur hosts. The catalytic sulfur host with Cu single atoms demonstrates high capacities and stable Coulombic efficiency, attributed to the relatively weak Cu-S bonding and low overpotential of solid-state sulfide conversion.

Summary: This study presents a metal-organic framework (MOF) with less-coordinated copper dimers, which exhibits excellent electrochemical CO2 reduction (eCO(2)RR) performance with a current density of 0.9 A cm(-2) and a Faradaic efficiency of 71% to C-2 products. Compared to MOF with Cu monomers, Cu dimers have a lower coordination number and favor the dimerization of *CO intermediates via *CH2CHO. The highly unsaturated dual-atomic Cu provides abundant and high-quality active sites for carbon-carbon coupling, achieving the optimal balance between activity and selectivity of eCO(2)RR to C-2 products.

Summary: A real-time tandem partial methane oxidation reaction (MOR) with cascaded plasma and electrocatalysis is reported for the first time, achieving activation and conversion of methane (CH4) synergistically. By using commercial Pd-based electrocatalysts, boosted CH4 conversion to value-added products is demonstrated. The mild condition, with anode potential < 1.0 V versus RHE, mitigates overoxidation of oxygenates and obviates competing reactions.
