Nitrogen-Doped Graphene Uniformly Loaded with Large Interlayer Spacing MoS Nanoflowers for Enhanced Lithium-Sulfur Battery Performance.

Lithium-sulfur (Li-S) batteries offer a high theoretical energy density but suffer from poor cycling stability and polysulfide shuttling, which limits their practical application. To address these challenges, we developed a PANI-modified MoS-NG composite, where MoS nanoflowers were uniformly grown on graphene oxide (GO) through PANI modification, resulting in an increased interlayer spacing of MoS. This expanded spacing exposed more active sites, enhancing polysulfide adsorption and catalytic conversion.

Facet Engineering-Induced Construction of NiP/ZnInS Heterostructures for Boosted Photocatalytic CO Reduction.

Facet engineering was realized to enhance the CO photoreduction performance of the NiP/ZnInS heterostructure, in which the commonly exposed (1 0 2) face of ZnInS was converted to the (1 0 1) face due to the unique properties of the phosphide. The variation in the crystal plane strengthened the intense interfacial contact between NiP and ZnInS, resulting in the promotion of utilization and absorption efficiency for incident light and boosting the surface reaction rate. Combined with the significant metallicity of NiP, inhibited recombination and strengthened transfer efficiency were achieved, leading to an obvious enhancement of photoreduction activity over NiP/ZnInS compared to pure samples.

Surface engineering of ultrasmall supported PdBi nanoalloys with enhanced electrocatalytic activity for selective alcohol oxidation.

Ultrasmall and homogeneous bimetallic PdxBi nanoalloys are well distributed on a Vulcan carbon support by a facile, low-cost synthetic strategy. The electrochemical activity of the as-prepared homogeneous PdxBi nanoalloy/carbon black nanocomposites is closely related to the content of Bi, revealing their excellent electrocatalytic performance for selective oxidation of monohydric alcohols and vicinal diols in alkali medium.
