Nb1.30Cr0.70S5: a layered ternary mixed-metal sulfide

The new layered ternary sulfide, Nb(1.30)Cr(0.70)S(5), niobium chromium penta-sulfide, is isostructural with the solid solution Nb(1+x)V(1-x)S(5) and belongs to the FeNb(3)Se(10) structure type. Each layer is composed of two unique chains of face-sharing [NbS(8)] bicapped trigonal prisms (m symmetry) and edge-sharing [MS(6)] (M= Nb, Cr) octa-hedra (m symmetry). One of the two metal sites is occ...

Ternary transition metal chalcogenides with framework structures and the characterization of their bonding by magnetic properties

An extended Zinti principle is discussed for framework structures of ternary metal chalcogenides, pnictides and hydrides with tetrahedral and planar coordination of transition metal atoms. Their bonding can be characterized by the magnetic moments measured by susceptibilities and neutron diffraction. The experimental results are compared with crystal field splittings obtained by calculations ba...

Fabrication of amorphous CoMoS4 as a bifunctional electrocatalyst for water splitting under strong alkaline conditions.

With the socio economic development, people have paid more and more attention to energy source problems, especially to clean and renewable energy such as hydrogen. It is appealing but still challenging to find or design an appropriate catalyst which is inexpensive and efficient for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in the same electrolyte. In this wo...

An advanced Ni-Fe layered double hydroxide electrocatalyst for water oxidation.

Highly active, durable, and cost-effective electrocatalysts for water oxidation to evolve oxygen gas hold a key to a range of renewable energy solutions, including water-splitting and rechargeable metal-air batteries. Here, we report the synthesis of ultrathin nickel-iron layered double hydroxide (NiFe-LDH) nanoplates on mildly oxidized multiwalled carbon nanotubes (CNTs). Incorporation of Fe i...
