Influence of carbon-chloride surface complexes on the properties of tungsten oxide supported on activated carbons.2. Surface acidity and skeletal
Article Abstract:
Chlorinated activated carbons and the respective tungsten oxide catalysts supported on them were tested, as catalysts in the decomposition reaction of 2-propanol and characterized by measurement of their pH (sub PZC), the supported catalysts were also used in the skeletal isomerization of 1-butene. Results showed that an increase in the chlorine contest of the support increases the total surface acidity, as measured by pH (sub PZC).

Influence of carbon-chloride surface complexes on the properties of tungsten oxide supported on activated carbons.1.dispersion, distribution, and chemical nature of the metal oxide phase
Article Abstract:
Different tungsten oxide catalysts supported on chlorinated activated carbons were prepared by using ammonium tungstate and tungsten pentaethoxide as precursor compounds. The results indicated that tungsten oxide is anchored to chlorine surface complexes through the formation of W-CI bonds during either the preparation or wet air pretreatment of the catalysts.

Analysis of blackbody-like radiation from laser-heated gas-phase tungsten nanoparticles
Article Abstract:
Thermal (blackbody-like) radiation that originated from laser-heated tungsten nanoparicles was measured using optical emission spectroscopy. The cooling rate and temperature data indicate that depending on experimental parameters, evaporation and surface reactions can have a definite effect on the growth of particles.
