The surface analytical characterization of carbon fibers functionalized by H2…
Abstract. A systematic, time-dependent, surface-sensitive study has, for the first time, given new insights into the mechanism of the often-used, but unexplained, sulfuric/nitric acid oxidation of graphene-containing materials, such as carbon fibers and carbon nanotubes. We used X-ray photoelectron, photoacoustic FTIR and Raman spectroscopies to follow the evolution of the functionalizatio…

Promotion effect of lanthanum addition on the catalytic activity of zirconia …
Abstract. Zirconia supported platinumand tungstophosphoric acid (TPA) metal-acid bifunctional catalystsmodified with lanthanum were prepared and tested in the reaction involving the production of branched-chain alkanes by skeletal isomerization of n-pentane. The prepared samples were characterized by XRD, FT-IR, H2-TPR andXPS. Thecatalytic performancewasevaluated at 200 oC underatmospheric …

Luminescent Properties in Relation to Controllable Phase and Morphology of Lu…
The calcite and vaterite type LuBO3:Eu3+ nano/microcrystals with various morphologies were synthesized by the hydrothermal (HT) approach through controlling the pH values of the precursor solutions. The calcite type LuBO3:Eu3+ shows the dominant magnetic dipole 5D0-7F1 emission due to S6 inversion symmetry of Lu. It also shows a symmetrical O-Eu charge transfer (CT) excitation band, which, …
