α‐Al2O3 is a widely utilized material with diverse technological applications, particularly as catalyst support in heterogeneous catalysis. Here, we present systematic investigation of the interaction between CO and α‐Al2O3(0001) single‐crystal surface by combining polarization‐resolved infrared reflection absorption spectroscopy theoretical calculations. The latter includes comprehensive analysis multiple coverage scenarios using periodic density functional theory calculations, well various...
The tumor-selective drug delivery system based on supramolecular micelles that were self-assembled by amphiphilic β-cyclodextrins (β-CD) with redox-responsiveness and fluorescence have been developed. β-CD formed anthraquinone (AQ) cyclodextrins disulfide bond in between. is charge of the responsiveness, while AQ moiety serves as fluorescent probe. tumor targeting was introduced host-guest inclusion complex between folate (FA), due to known folate-receptor mediated endocytosis. responsive...
We studied the adsorption of CO on Pd/Pt nanoparticles (NPs) with varying compositions using polarization-dependent Fourier transform infrared reflection absorption spectroscopy (FT-IRRAS) and theoretical calculations (DFT). prepared PtPd alloy NPs via physical vapor codeposition α-Al2O3(0001) supports. Our morphological structural characterization by scanning electron microscopy grazing incidence X-ray diffraction revealed well-defined, epitaxial NPs. used as a probe molecule to identify...
We report a type of termination the $\ensuremath{\alpha}\text{\ensuremath{-}}{\mathrm{Al}}_{2}{\mathrm{O}}_{3}(0001)$ surface with low concentration hydroxyl groups. Using density functional theory calculations, we show that this is more stable than previously reported structures for chemical potentials water. This means groups remain thermodynamically up to much higher temperatures predicted previously, example, around 1000 K at 1 mbar partial pressure also study formation these...
We studied the adsorption of CO on PdPt nanoparticles with different metal ratio using theoretical calculations (DFT) and experimental investigations. A model catalyst was employed, where platinum (Pt) palladium (Pd) were co-deposited via physical vapor deposition surface α-Al2O3(0001). used as a probe molecule for particles’ composition. Polarized infrared reflection absorption spectroscopy (FT-IRRAS) enabled observation top side facets. The role Pd/Pt alloy investigated by comparing...
