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:
... Increasing the utilization efficiency of noble metals by the synergy with less expensive metals is an important yet challenging issue in heterogeneous catalysis. Herein, exemplified with Pt-catalyzed hydrolytic dehydrogenation of ammonia borane, partial substitution of the Pt catalysts by over 11 times less expensive Ru is studied to obtain highly efficient and cost-effective Pt-based catalysts. I ...

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. ...
