Abstract

Herein, we report the first ever eco-friendly and easy

synthesis of carboxymethyl cellulose-stabilized RuCo nanoclusters

(Ru0.57Co0.43@CMC) and their use as highly efficient and durable

catalysts to produce hydrogen from hydrolytic dehydrogenation of

methylamine borane (MeAB). Ru0.57Co0.43@CMC nanoclusters are

easily synthesized from synchronous chemical reduction of suitable

water-soluble cobalt and ruthenium salts by sodium borohydride.

They are identified by some advanced methods including ultraviolet−

visible spectroscopy, transmission electron microscopy, and X-ray

photoelectron spectroscopy. All related kinetic studies show that

Ru0.57Co0.43@CMC nanoclusters are extremely efficient, relatively

cost-saver, and durable catalysts in hydrolytic dehydrogenation of

MeAB at very low temperatures. They provided the highest ever

initial turnover frequency value of 327.1 min−1 and also the apparent

activation energy of 49.7 kJ/mol for the hydrolytic dehydrogenation of MeAB.
