Addressed herein, we report the development of carbon nanotube furnished highly efficient and nearly monodisperse Pt(0) nanocatalysts for both C1 to C3 alcohol oxidation and the dehydrocoupling of dimethylamine borane (DMAB) which is considered to be one of the new hydrogen storage materials. The ultrasonication method was employed to increase platinum (Pt) NPs dispersion on carbon nanotube (CNTs). The data show that the route is very effective for uniform distribution of Pt NPs on nanotubes and for agglomeration problem of platinum. The prepared nearly monodisperse nanomaterials have been characterized by ICP-OES, XRD, TEM, HR-TEM and XPS techniques. The catalytic performances of carbon nanotube furnished highly efficient and nearly monodisperse Pt(0) nano-catalystsin terms of activity, life-time and reusability performances have been investigated for both the catalytic dehydrocoupling of dimethylamine-borane and C1 to C3 alcohol oxidation reactions in THE at room temperature. All results show that highly crystalline and colloidally stable nanomaterials and they were found to be one of the most active and the long-lived catalysts with extraordinary reusability performance in the dehydrocoupling of DMAB and C1 to C3 alcohol oxidation reactions at room temperature.
