  - POLYHEDRON - Year 2018

  A series of four novel transition metal complexes, [Cu(NCS)2L1] (1), [Mn(NCS)2L1] (2) where L1 = bis(1-(3,5-dimethylpyrazolyl)methyl)amine, [Mn(NCS)2L2] (3) and [Zn(NCS)L2]2[Zn(NCS)4] (4) where L2 = tris(1-(3,5-dimethylpyrazolyl)methyl)amine, has been obtained in situ by a one-step, one-pot synthetic path starting from 1-hydroxymethyl-3,5-dimethylpyrazole (L). The isolated complexes were fully characterised by elemental analysis,...

  This study investigates Ni-based compounds (Ni, NiO, Ni3C) coated with a graphitic shell as electrocatalysts for the oxygen evolution reaction (OER). Electron paramagnetic resonance (EPR) and X-ray diffraction (XRD) are employed to identify the presence and contribution of Nickel ions (Ni0, Ni2+, Ni3+) and determine the phase composition. Electrochemical...

  Data contain EPR spectra of TiO2 (anatase phase) heat treated in H2 at 500 and 600oC. Sample heated at 500oC contained 4 wt% of rutile and that at 600oC 8 wt% of rutile.

• Physicochemical and photocatalytic data of Nb-doped faceted TiO2

  Raw numerical data, obtained from the physicochemical measurements (XRD, DR-UV/Vis, EPR) and numerical data on photocatalytic activity (phenol degradation and 4-nitrophenol reduction) extracted from the HPLC-DAD results, obtained for the TiO2 nanoparticles that expose majority of the {0 0 1}, {1 0 0} or {1 0 1} facets and were doped with the nominal...

  - APPLIED CATALYSIS B-ENVIRONMENTAL - Year 2014

  Bimetallic nanoparticles, composed of two different metal elements, can exhibit peculiar electronic, optical, and catalytic or photocatalytic properties that are absent in the corresponding monometallic nanoparticles. We show the effect of calcination temperature (from 350 to 700°C) on the structure and the photocatalytic properties of Au/Pd-modified TiO2. The composition of the bimetallic Au/Pd nanoparticles in relation to their...
