Abstract:
... We demonstrate an unprecedented H₂ generation activity in the hydrolytic dehydrogenation of ammonia borane over acid oxidation- and subsequent high temperature-treated CNT immobilized Pt nanocatalysts to combine the merits of defect-rich and oxygen group-deficient surfaces and unique textural properties of supports as well as optimum particle size of Pt. ...

Abstract:
... Five types of carbon materials, including carbon nanotubes (CNTs), carbon nanofibres, carbon black, activated carbon and graphite, were evaluated in searching for an appropriate support for a Pt catalyst used for the dehydrogenation of decalin under microwave irradiation (MW). The thermal behaviour of different carbon materials and supported Pt catalysts suspended in decalin under MW was investiga ...

Abstract:
... We report a size-dependent activity in Pt/CNT catalyzed hydrolytic dehydrogenation of ammonia borane. Kinetic study and model calculations revealed that Pt(111) facet is the dominating catalytically active surface. There is an optimized Pt particle size of ca. 1.8 nm. Meanwhile, the catalyst durability was found to be highly sensitive to the Pt particle size. The smaller Pt particles appear to hav ...
