Facile synthesis of copper sulfides on copper foam as an efficient electrocatalyst for oxygen evolution reactionNano-structured Cu2S catalyst was successfully fabricated on copper foam (Cu2S-CF) via a facile method. The SEM results demonstrated that the Cu2S possessed nanoparticle- and nanoflake-shaped...

The size of produced primary particles varied from 10 to 200 nm. Particle crystallinity was found to depend on both the oxygen concentration and the furnace temperature. A model taking into account the detailed chemical reaction mechanisms during the particle formation is proposed. The model allows ...
A concise and efficient aerobic oxidation and oxygenation approach for the construction of 2-aroylquinolines has been developed through copper-catalyzed annulation of anilines, acetaldehydes, and dioxygen. 2,2,6,6-Tetramethylpiperidine-1-oxyl was employed to direct the selectivity toward the desired...
A copper-catalyzed tandem reaction with vinyl halides and 2-aminobenzamides has been developed. In this synthetic route, cross-coupling reaction of the amide moiety with vinyl halides initially progresses, followed by hydroamination, to provide 2,2-disubstituted quinazolinone derivatives. Moreover, the...
An efficient methodology has been developed for the synthesis of nitriles through an aerobic oxidative reaction of alcohols and ammonium formate with copper as a homogeneous catalyst under a normal air atmosphere and solvent-free conditions. This protocol uses the air as a green oxidant and ammonium...

1c). It affords a general route to aromatic ketones from two easily accessible coupling partners without the involvement of air-sensitive reagents and harsh reaction conditions. This protocol allows practical and friendly reaction conditions which significantly broadens the substrate scope and emphasizes ...
