We have used X-ray photoelectron spectroscopy to study the effects of chlorine gas on Fe and Fe203 surfaces pre-exposed to H2S at 105 K. H2S chemisorbs on the Fe203 surface at 105 K to form adsorbed sulfur (S,) and sulfylhydril (SH,) intermediates. Subsequent exposure to C12 vapor at 105 K results i

CycIic vohammetry was applied to investigate the Cr" KY' and Fe" /Fe:+ redox couple reactions in HCI electrolytes on highly oriented pyrographite electrodes activated by oxidative pretreatment. The activation effect observed after the oxidative pretreatment was very unstable for the Cr"/C?+ reaction
## Abstract Carbon nanofibers (CNFs) are grown by catalytic CO disproportionation over ultrafine Fe~3~O~4~ catalyst at a hydrogen concentration of 0โ29.17%, and the timeโdepending rates of CNFs growth are continuously monitored and the morphologies of the asโsynthesized CNFs are analyzed. Increasin
## Abstract The preparation and H~2~S sensing potential of thickโfilms of a mixed oxide, Fe~2~O~3~๏ฃฟFe~2~(MoO~4~)~3~, were investigated. A Fourierโtransform infrared (FTIR) study confirmed the existence of sulfur species at the surface after the interaction of H~2~S gas with the mixed oxide. The sta
A ~ianthrene-anthracene mixture has been used to study the influence of Fe@, addition in suppressing the volume expansion of carbons due to suifur release on heat treatment. For undoped carbons, the particle density began to decrease above about 1200ยฐC and continued to 2500ยฐC. There was an accompany
