Layered Transition-Metal Ditellurides in Electrocatalytic Applications-Contrasting Properties

The layered compounds and especially transition-metal dichalcogenides are at the forefront of current research on electrocatalytic materials. Despite the fact that electrocatalytical properties of molybdenum and tungsten disulfides are well-known, their tellurium analogues are significantly less explored. Here we show an effective method for MoTe2 and WTe2 chemical exfoliation based on alkali metal intercalation and …

Unconventionally Layered CoTe2 and NiTe2 as Electrocatalysts for Hydrogen Evolution

Two members of the transition metal ditelluride family, CoTe2 and NiTe2, exist in multiple structures encompassing marcasite-, pyrite- and CdI2 related structures. The allotrope modification is influenced by weak changes in stoichiometry and synthesis. It is crucial to emphasize that the CdI2 structure type is manifested by NiTe2 while the CoTe2 adopts a related structure …
