Modulating heterointerfaces of tungsten incorporated CoSe/Co₃O₄as a highly efficient electrocatalyst for overall water splitting

When NiO@Ni Meets WS2 Nanosheet Array: A Highly Efficient and Ultrastable Electrocatalyst for Overall Water Splitting

The development of low-cost, high-efficiency, and stable bifunctional electrocatalysts toward the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is of paramount importance for large-scale water splitting. Here, we develop a new strategy for the first design and synthesis of a NiO@Ni decorated WS2 nanosheet array on carbon cloth (NiO@Ni/WS2/CC) composite. This composite se...

Tungsten carbide nanoparticles as efficient cocatalysts for photocatalytic overall water splitting.

Tungsten carbide exhibits platinum-like behavior, which makes it an interesting potential substitute for noble metals in catalytic applications. Tungsten carbide nanocrystals (≈5 nm) are directly synthesized through the reaction of tungsten precursors with mesoporous graphitic C(3)N(4) (mpg-C(3)N(4)) as the reactive template in a flow of inert gas at high temperatures. Systematic experiments th...

Water Splitting: Porous Nickel–Iron Oxide as a Highly Efficient Electrocatalyst for Oxygen Evolution Reaction (Adv. Sci. 10/2015)

Electrocatalyst decorated hematite nanowire arrays for photoelectrochemical water splitting

A highly efficient electrocatalyst for the oxygen reduction reaction: N-doped ketjenblack incorporated into Fe/Fe3C-functionalized melamine foam.

Polarization caused by the oxygen reduction reaction (ORR) on cathodes still contributes significantly to the energy efficiency loss of metal–air batteries and fuel cells. Thus, ways of increasing the ORR kinetics while maintaining fast mass transfer is a grand challenge in the development of a new generation of metal–air batteries and fuel cells. Catalysts based on platinum and other precious ...
