In this work, the process of the subsequent intercalation of HSO4H2SO4into CrO3-GIC examined. CrO3GICICs are prepared with two different chemical methods: this is, intercalation from the CrO3/CH3COOH solution according to the Platzcr and de la Martiniere procedure and intercalation of CrO3from Cr03/HCl solution. Furthermore, the preparation of graphite multiintercalation compound consisted with two...
The aim of this work was to study the electrochemical properties of exfoliated graphite (EG)/Ni/NiO composite. Composite material subjected to the investigations was obtained according to a three-step synthesis. In the first step the electrochemical intercalation of sulfuric acid into the natural graphite with formation of graphite intercalation compound with sulfuric acid (H(2)SO(4)-GIC) was performed...
Successful trial was conducted of synthesis of two new bi-intercalation compounds: ZnCl2-FeCl3-fiZG and ZnCl(2)-FeCl(3)-H(2)SO(4)-BZG. ZnCl(3)-IZG with intercalation stage n = 5 was selected as initial compound, characterised by a great admixture of a pure graphite phase. Synthesis of ZnCl(2) was conducted in 4,8 M, solution of FeCl(3) in nitro-methane. The method of X-ray diffraction analysis served...
Przeprowadzono chemiczną modyfikację aktywowanych włókien węglowych w roztworze CrO(3)-lodowaty CH(3)COOH, a następnie zbadano elektrochemiczne właściwości otrzymanego materiału elektrodowego w roztworze alkalicznym. Główną uwagę poświęcono aktywności elektrochemicznej modyfikowanych włókien w modelowej reakcji utleniania fenolu.
Przeprowadzono badania wpływu kwasu mrówkowego na przebieg procesu intcrkalacji HClO(4) w grafit łuskowy oraz intcrkalacyjny związek grafitu z trójtlenkiem chromu (Cr0(3)-IZG), charakteryzujący się stadium interkalacji 4. W celu wyjaśnienia mechanizmu reakcji przeprowadzono analizę rentgenowską otrzymanych związków oraz wykonano cykliczne pomiary woltamperometryczne. Uzyskane wyniki badań wykazały,...
