AI Article Synopsis
- The study explores a new method to enhance catalytic activity by using a stable electride combined with bimetallic nanoparticles, specifically a Ru-Fe nano-alloy.
- The electride [CaAlO]·(e) has a low work function, increasing the catalyst's effectiveness in converting α,β-unsaturated aldehydes to unsaturated alcohols without the need for solvents.
- The synergistic effect between the electride and the nanoparticles allows for better H dissociation and the preferred adsorption of specific chemical bonds, making it possible to produce valuable chemicals that are otherwise difficult to obtain.
Article Abstract
Controlling the electronic structure of heterogeneous metal catalysts is considered an efficient method to optimize catalytic activity. Here, we introduce a new electronic effect induced by the synergy of a stable electride and bimetallic nanoparticles for a chemoselective reduction reaction. The electride [CaAlO]·(e), with extremely low work function, promotes the superior activity and selectivity of a Ru-Fe nano-alloy for the conversion of α,β-unsaturated aldehydes to unsaturated alcohols in a solvent-free system. The catalyst is easily separable from the product solution and reusable without notable deactivation. Mechanistic studies demonstrate that electron injection from the electride to the Ru-Fe bimetallic nanoparticles promotes H dissociation on the highly charged active metal and preferential adsorption of C[double bond, length as m-dash]O bonds over C[double bond, length as m-dash]Cs bond of the unsaturated aldehydes, to obtain the thermodynamically unfavorable but industrially important product.

Two-dimensional (2D) nanomaterials have garnered extensive attention owing to their unique properties and versatile application. Here, a family of 2D rare-earth metal phosphides (MP, M = Sc, Y, La) and their derivatives MPOT (T = F, OH) is developed to find their topological and electronic properties on the basis of density functional theory simulations. We show that the 2D MP compounds are most possibly obtained from thermodynamically stable MInP by chemical exfoliation.

Article Synopsis
- An electride, featuring interstitial anionic electrons (IAEs), shows potential in improving superconductivity by altering interactions under high pressure.
- Current research has mostly focused on pressures up to 300 GPa, but studying the Li-S system at even higher pressures may reveal new superconducting electrides.
- Specifically, the 2/ LiS phase at 600 GPa displays unique IAE properties and achieves a superconducting transition temperature of 53.29 K, due to interactions among S, Li electrons, and IAEs.

The commercial viability of emerging lithium-sulfur batteries (LSBs) remains greatly hindered by short lifespans caused by electrically insulating sulfur, lithium polysulfides (LiS; 1 ≤ ≤ 8) shuttling, and sluggish sulfur reduction reactions (SRRs). This work proposes the utilization of a hybrid composed of sulfiphilic MoS and mayenite electride (C12A7:e) as a cathode host to address these challenges. Specifically, abundant cement-based C12A7:e is the most stable inorganic electride, possessing the ultimate electrical conductivity and low work function.

An electride is a compound that contains a localized electron in an empty crystallographic site. This class of materials has a wide range of applications, including superconductivity, batteries, photonics, and catalysis. Both polymorphs of YbSb (the orthorhombic CaSbF structure type (β phase) and hexagonal MnSi structure type (α phase)) are known to be electrides with electrons localized in 0D tetrahedral cavities and 1D octahedral chains, respectively.
