The inclusion complex formation of irisquinone with hydroxypropyl-beta-cyclodextrin(HP-beta-CD) and the physico- chemical properties were studied. Complex of host molecules with irisquinoe was studied by x-ray diffraction (XRD) and differential scanning calorimetry(DSC). The quantitative analysis with uv-vis indicated that HP-beta-CD could increase the solubility of irisquinone, where the best results was given with HP-beta-CD :irisquinone 2:1 molar ratio. The binding constants of inclusion complex formulation were obtained with relative Higuchi Principle and thermodynamics equation.
Nitrogen-doped TiO 2 (N/TiO 2 ) photocatalysts were prepared using a mechanochemical method with raw amorphous TiO 2 as precursors and various nitrogenous compounds doses (NH 4 F, NH 4 HCO 3 , NH 3 ·H 2 O, NH 4 COOCH 3 , and CH 4 N 2 O). The photocatalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), thermal gravimetric-differential thermal analysis (TG-DTA), and UV-Vis diffuse reflection spectra (UV-Vis-DRS). Their photocatalytic activities were evaluated with the degradation of p-nitrophenol and methyl orange under UV or sunlight irradiation. The catalysts had a strong visible light absorption which correspond to doped nitrogen and consequent oxygen deficient. The results of photocatalytic activity showed the visible light adsorption mechanisms, as the doped nitrogen species gave rise to a mid-gap level slightly above the top of the (O-2p) valence band, but not from the mixed band gap of the N-2p and O-2p electronic levels.
