## Abstract Carbon nanofibers (CNFs) are grown by catalytic CO disproportionation over ultrafine Fe~3~O~4~ catalyst at a hydrogen concentration of 0β29.17%, and the timeβdepending rates of CNFs growth are continuously monitored and the morphologies of the asβsynthesized CNFs are analyzed. Increasin

The hydrogenation of catalytic carbons has been studied in the temperature range of their deposition (300-700Β°C) by CO disproportionation or by CH4 decomposition on nickel powders. When obtained under non carbiding conditions, the catalytic carbons are very reactive between 350 and 600Β°C where uncat
A series of catalytic carbons has been prepared by CO disproportionation (2CO + CO> + C) over an iron nickel catalyst. The catalyst is under the form of filings (particle sizes ranging from IO to 160 ym) of an iron nickel alloy (75 wt % nickel, 25 wt % iron). The dependence of the rate of carbon dep
