One-dimensional
(1D) hybrid nanostructures composed of silver/silver
sulfide (Ag/Ag2S) and zinc sulfide (ZnS) were prepared
by controllable migration of Ag species from the Ag nanowire (NW)
core into the ZnS nanosheet shell. This Ag diffusion process can be
manipulated by different concentrations of sulfur (thiourea) to realize
various interspersion of Ag2S with ZnS. Because of the
homogeneous dispersion of Ag with ZnS at the lattice scale, the as-formed
1D nanostructures have demonstrated red/blue light-enhanced electrocatalytic
properties for water splitting. In addition, the Ag interspersion
has enabled ZnS sensitivity to visible light, which results in efficient
1D hybrid materials for photocatalytic hydrogen (H2) production
under visible light. In this work, we have designed and explored an
Ag migration method to prepare 1D core–shell nanostructures
for bifunctional catalysis.
The lithium iron silicate, Li2FeSiO4, is a promising cathode material for lithium ion batteries due to its high theoretical specific capacity, earth abundance, low cost, and environmental friendliness. The challenges...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
