Abstract
Several metal nanoparticle based catalysts have been synthesized for
catalyzing the hydrogen production process by hydrolysis of methylamine-borane
(MeAB). However, there was only one study that catalyzes the producing of hydrogenvia the methanolysis of MeAB, and it was
carried out by our research group. For this reason, in this work, a new catalyst
system entitled by single-walled carbon nanotube (SWCNT) supported bimetallic
platinum-ruthenium nanoparticles were developed and called as PtRu@SWCNT. These NPs
were characterized by several techniques (XRD, XPS, Raman, and TEM), and they were
performed for the methanolysis of MeAB with high catalytic activity. The prepared
PtRu@SWCNT NPs were also tested in the methanolysis of MeAB at different parameters
including different temperatures, catalyst and substrate concentrations, and
reusability performance. Experimental results revealed that the new PtRu@SWCNT NPs
had excellent catalytic activity and reusability for removing of hydrogen from the
methanolysis of MeAB at ambient conditions. According to the obtained data, the
turnover frequency is 136.25 mole H2/mole PtRu × min, and the
activation energy (Ea) is 17.29 kJ/mole. More than 99% of conversion was observed at
room temperature.
