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.
