For comprehensive utilization of CO contained in closed carbide furnace tail gas, the purification of HCN in the artificial tail gas mixed with pure gases was studied by means of adsorption using modified activated carbon. In range of this study the optimum conditions for preparing modified activated carbon are: NaOH concentration is 10 wt% and sulfonated cobalt phthalocyanine (CoPcS) concentration...
Ball milling is an effective way of producing defective and nanostructured graphite. In this work, graphite was milled under 3 bar hydrogen in a tungsten carbide milling pot, and the effect of milling conditions on the microstructure and hydrogen storage properties was investigated by TGA-Mass Spectrometry, XRD, SEM and Raman spectroscopy. After milling for 10 hours, 5.5 wt% hydrogen was released...
Nanocarbon ensembles (NCE) composed of ultrananocrystalline diamond (UNCD) powders by reacting with methane at 1200 K are complementarily characterised by optical microscope (OM), Raman, fourier transform infrared spectroscopy (FT-IR), x-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). The porous bulk material of NCE are further confirmed to be composed of nanodiamond crystallites...
Summary form only given. The C/sub 60/ film samples were irradiated in air by XeCl laser. The sheet conductivities were determined by measuring the resistance between the two electrodes and plotted as a function of the number of laser shots. These data show an increase in conductivity of over, six orders of magnitude. Finally, the Raman spectroscopy and STM images of these laser-irradiated fullerene...
