Visible light sensitive photocatalysts, nitrogen-doped Ta2O5 powders

Article Abstract:

The photocatalytic activities of nitrogen-doped Ta2O5 powders, Ta2O(sub 5-x)N(sub x)(x=0.10, 0.17, 0.24, 0.35) were evaluated by the decomposition of gaseous 2-propanol (IPA) under visible (Vis) and ultraviolet (UV) light irradiations with the same absorbed photon number [1.4 x 10(super 14) quanta.cm(super -2.)sec(super -1)].

Structure and guest distribution of the mixed carbon dioxide and nitrogen hydrates as revealed by X-ray diffraction and (super 13)C NMR spectroscopy

Article Abstract:

X-ray diffraction and (super 13)C NMR spectroscopy are used to identify structure and guest distribution of the mixed N2 + CO2 hydrates. The corresponding hydrate phase compositions are measured as macroscopic approaches to complement the NMR spectroscopic results.

Study of nitrogen adsorbed on open-ended nanotube bundles

Article Abstract:

The adsorption of N2 on the open-ended single-walled carbon nanotube bundles was studied. It concludes that the binding energy of nitrogen on the open-ended nanotube was greater than that of nitrogen on the closed-ended nanotube bundles.
