Progress in catalysis is driven by society's needs. The development of new electrocatalysts to make renewable and clean fuels from abundant and easily accessible resources is among the most challenging and demanding tasks for today's scientists and enginee ...

Biocatalytic hydroamination of alkenes is an efficient and selective method to synthesize natural and unnatural amino acids. Phenylalanine ammonia-lyases (PALs) have been previously engineered to access a range of substituted phenylalanines and heteroaryla ...

Ketones are an important class of molecules in synthetic and medicinal chemistry. Rapid and modular synthesis of ketones remains in high demand. Described here is a nickel-catalyzed three-component reductive carbonylation method for the synthesis of dialky ...

The present invention relates to a nickel iron diselenide compound of general formula (I): NixFe1-xSe2, wherein 0 < x < 1, and to the use of this compound as a precursor of catalysts for oxygen evolution reaction (OER). This invention also concerns methods ...

Polydispersed dinickel phosphide (Ni2P) nanoparticles were synthesized by a simple and scalable solid-state reaction. These nanoparticles are an excellent and robust catalyst for the electrochemical hydrogen evolution reaction, operating in both acidic and ...

Hydrogenases are promising templates for constructing new H-2-based catalysts. [Fe]-hydrogenase, which features an ironguanylylpyridinol (FeGP) cofactor, catalyses a reversible hydride transfer from H-2 to methenyl-tetrahydromethanopterin (methenyl-H4MPT+, ...

Rarely reported low-cost molybdenum boride and carbide microparticles, both of which are available in abundant quantities due to their widespread use in industry, adsorb at aqueous acid–1,2-dichloroethane interfaces and efficiently catalyse the hydrogen ev ...

A simple protocol for iron-catalyzed cross-coupling of nonactivated secondary alkyl bromides and iodides with alkynyl Grignard reagents at room temperature has been developed. A wide range of secondary alkyl halides and terminal alkynes are tolerated to af ...
