Preparation and Activity on Unsupported Hydrotreating Catalysts.
Moravčík, Jan ; Gulková, Daniela ; Kaluža, Luděk
The aim of the present work is to investigate reactivity of precursors of CoMo and NiMo catalysts (molar ratio 0.3- Co/(Co-iMo) ol'Co or Ni) in aqueous solution with intention to prepare high surface area (ST) sulfides.
Fullerene C60 in Aqueous Medium
Kocábová, Jana ; Gál, Miroslav ; Hromadová, Magdaléna ; Kavan, Ladislav ; Pospíšil, Lubomír ; Sokolová, Romana
The aqueous solution of C60 was investigated by electrochemical and spectroscopis methods such as UV-Vis, Raman, FTIR and AFM techniques. The association constants of fullerene-gamma-cyclodextrin complex and ,ethanofullerene conjugates with beta-cyclodextrins in aqueous solution were evaluated from the shifts of the formal redox potential of complexed and uncomplexed fullerene. The most suitable techniques for electrochemical characterization of fullerene derivatives proved to be the low-frequency phase-sensitive AC polarography and the steady-state voltammetry.
