Carbon nanofibers synthesized by decomposition of alcohol at atmospheric pressure

In the present study, we fabricated the carbon nanofibers (CNFs) by decomposition of methyl alcohol at atmospheric pressure. The CNFs were grown on Ni/Si substrates using simplified hot-filament chemical vapor deposition equipment. The deposits mainly consist of the semicrystalline CNFs, in which a few of carbon nanotubes are included. On the 30-nm-thick Ni/Si substrates, the mean length of the CNFs is 2–3 μm, and their average diameter is less than 100 nm. The as-deposited CNFs were evaluated by both scanning and transmission electron microscopes. The field-electron-emission properties of CNFs were characterized as well.

Properties of the Cr2O3/MgF2 system — catalytical aspect

The influence of Cr2O3 on properties of the Cr2O3/MgF2 catalysts obtained by impregnation and precipitation-deposition is described. The IR technique enabled monitoring of changes in the structure of the MgF2 surface after introducing chromium ions. Tetrahedral chromium complexes as well as structures of Cr3O3 type were observed. The deposited species generated the Lewis and BrOnsted acidity which in turn was responsible for the catalytic activity in the reactions of 2-propanol decomposition, butene double bond isomerization, cumene cracking, dehydrogenation of cyclohexane and decomposition of methyl alcohol.

Reaction intermediates in methyl alcohol decomposition on ZnO

The decomposition of methyl alcohol on ZnO was studied using infra-red spectroscopy during the course of the reaction. The concentrations and reactivities of the chemisorbed and gas phase species were measured as well as the overall reaction rate under various non-stationary conditions. When CD3OD vapour was introduced over ZnO, methoxide ion and formate ion were observed, and D2, CO2 and CO were evolved into the gas phase. When the CD3OD in the ambient gas was removed by a dry ice-methyl alcohol trap during the course of the reaction, the evolution of D2 and CO2 stopped, while the evolution of CO continued unchanged. At 240°C, the decomposition rate of the surface formate ion was in reasonable agreement with the rate of production of carbon monoxide. On releasing the trapped methanol, the rates of formation of CO2 and D2 increased again, surface methoxide reappeared, and the concentration of the surface formate ion decreased correspondingly. These results lead to the conclusion that CO was produced mainly by the decomposition of formate ion, and D2 and CO2 came from the reaction between CD3OD and DCOO(a).

On the oxidation of methyl and ethyl alcohol. The mechanism of reaction in the gas phase

AbstractThe oxidation of methyl alcohol has been investigated in the liquid phase and the gas phase. In the latter case copper and aluminium were used as catalysts. Also the decomposition of methyl alcohol was investigated, oxygen being absent. These experiments were repeated using no catalyst.Some experiments were made on the oxidation of ethyl alcohol in the gas phase and on the reduction of carbon monoxide with hydrogen.
