Abstract:
... Controllable synthesis of graphite oxide (GO) for targeted surface properties is of great importance for its versatile applications. For this purpose, GO samples were prepared with different amounts of oxidant and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, ¹³C cross-polarization with total sideband suppression magic-angle-spinning nuclear magnetic resonance, X-ray ...

Subject:
adsorption; ammonia; catalysts; dehydrogenation; durability; hydrogen production; models; particle size; platinum
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 ...

Subject:
active sites; carbon nanotubes; catalysts; engineering; glyceraldehyde; glycerol; nanoparticles; oxidation; particle size; platinum
Abstract:
... Different sized Pt nanoparticles supported on carbon nanotubes were prepared and then applied in selective oxidation of glycerol in a base-free condition to understand the size effects. It is shown that the turnover frequency of glycerol increases with Pt particle size to a maximum at the mean size of 2.5 nm followed by a decline with a further increase in size, which may be due to strongly adsorb ...
