Abstract:
Trimetallic core-shell Cu@CoNi nanoparticles (NPs) supported on graphene with different compositions are synthesized through a one-step in situ reduction process by using methylamine borane (MeAB) as a reducing agent. The as-synthesized Cu-core/CoNi-shell NPs are well dispersed on graphene. Among the catalysts studied, Cu0.1 @Co0.45 Ni0.45 /graphene displays the highest catalytic performance toward the hydrolysis of ammonia borane (AB), with a turnover frequency (TOF) value of 15.46 mol H2 min-1 (mol catalyst)-1 , which is higher than those of most reported non-noble-metal-based NPs, and even higher than many noble-metal-based NPs. Additionally, the as-synthesized Cu0.1 @Co0.45 Ni0.45 /graphene NPs reduced by MeAB exhibit a higher catalytic activity than those reduced by NaBH4 and AB. Furthermore, the as-prepared NPs have good durability and magnetic recyclability for the hydrolytic dehydrogenation of AB and MeAB.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
