Resumen

Los catalizadores de átomo único en soporte de carbono mejoran las baterías de iones de sodio basadas en MoS2 al mejorar la reversibilidad de Na2S. Los catalizadores con afinidad por S debilitan los enlaces Na-S, mejorando el rendimiento y la vida útil de la batería.

Sus antecedentes:

Las baterías de iones de sodio basadas en MoS2 enfrentan desafíos con reacciones irreversibles.
Los catalizadores de átomo único (C-SAM) convencionales a menudo predicen erróneamente la adsorción de Na2S debido a que descuidan los enlaces Na-N y la deformación estructural.

Conclusiones:

Los C-SAM con afinidad por el azufre son efectivos para mejorar la reversibilidad de las baterías de iones de sodio basadas en MoS2.
El método desarrollado proporciona un nuevo enfoque para el diseño de catalizadores avanzados.
Los electrodos de MoS2/C-SAV demostraron una excelente estabilidad a largo plazo y una alta retención de capacidad.

Preparation and Reactions of Sulfides

Preparation and Reactions of Sulfides

Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

Reduction of Alkynes to trans-Alkenes: Sodium in Liquid Ammonia

Reduction of Alkynes to trans-Alkenes: Sodium in Liquid Ammonia

Alkynes can be reduced to trans-alkenes using sodium or lithium in liquid ammonia. The reaction, known as dissolving metal reduction, proceeds with an anti addition of hydrogen across the carbon–carbon triple bond to form the trans product. Since ammonia exists as a gas (bp = −33°C) at room temperature, the reaction is carried out at low temperatures using a mixture of dry ice (sublimes at −78°C) and acetone.
When dissolved in liquid ammonia, an alkali metal, such as sodium,...

Formation of Complex Ions

Formation of Complex Ions

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
