Phase‐Engineered MoS2 Quantum Monolayer Catalysts

Advanced Materials, EarlyView.
A new type of catalyst model—phase‐engineered MoS2 quantum‐monolayer catalyst (∼0.8 nm thick, < 6 nm in the lateral size; switchable freely among metallic 1T, semiconducting 2H, and a hybrid phase of metallic‐semiconducting 1T‐2H)—is reported. It can efficiently and stably drive photochemical H2, syngas and ammonia synthesis as a catalyst or co ...

Design of High‐Energy Anode for All‐Solid‐State Lithium Batteries–A Model with Borohydride‐Based Electrolytes

Advanced Materials Interfaces, EarlyView.
This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

Advanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Ball‐Milling Assisted Synthesis of Monofluoroalkenes

Chemistry – A European Journal
AbstractA solvent‐free synthesis of valuable monofluoroalkenes was developed under ball‐milling agitation. The use of 1.0 equivalent of carbonyl substrates and 1.1 equivalent of fluorophosphonoacetate derivatives with a weak inorganic base enabled the formation of the desired products after 30 min of reaction under sustainable conditions with minimized
