Two different nanomaterial-based metallophthalocyanine catalysts were synthesized by immobilizing iron trinitrophthalocyanine with amino (FeMATNPc) covalently on multi-walled carbon nanotubes (MWCNTs) by deamination-synthesized MWCNTs-FeTNPc and on oxidized MWCNTs by amidation-synthesized MWCNTs–CONH–FeTNPc. The resulting hybrid structure was confirmed and characterized by X-ray photoelectron spectroscopy...
A new type of low carbon Al2O3 refractory material was prepared using coarse-grain white fused alumina, tabular alumina (⩽0.043mm), graphite flake (⩽0.147mm), silicon powder (⩽0.074mm) and carbon nanotubes (CNTs) as fillers, and thermosetting phenolic resol as binder. The CNTs were added directly to the fillers or coated onto tabular alumina by catalytic chemical vapor deposition (CVD). Properties...
Carbon black (CB) and carbon nanotubes (CNTs) were used as additives in phenolic resin. The effects of the additives and heat treatment temperature on the oxidation resistance and structure of carbon from the pyrolysed phenolic resin were investigated by differential scanning calorimetric analysis, X-ray diffraction, scanning electron microscopy, and mercury intrusion porosimetry. It was observed...
A nanomaterial-based metallophthalocyanine catalyst (CoTAPc-MWCNTs) was prepared by covalently immobilizing cobalt tetraaminophthalocyanine (CoTAPc) on multiwalled carbon nanotubes (MWCNTs). The decomposition reaction of H 2 O 2 was chosen to investigate the coupled catalytic performance. The results of electron paramagnetic resonance and online electrochemical experiments indicated...
Single-wall carbon nanohorns (SWCNHs) with different morphologies were generated by direct current arc-discharge between pure graphite rods in different atmospheres, including air, CO 2 and CO. In the arc-discharge process, the O 2 in the air reacted with carbon atoms and transformed into CO so that the formation of SWCNHs was a result of a combination of CO and N 2 . The effect...
N-doped multi-layered graphene sheets were synthesized in large scale by the method of direct current arc-discharge between pure graphite rods. For the use of NH 3 as one of the buffer gas, the multi-layered graphene sheets were doped with N without the addition of other nitrogen source. The product so obtained has been characterized by transmission electron microscopy, Raman spectroscopy,...
Multiwalled carbon nanotubes (MWCNTs) used to support a metallophthalocyanine catalyst (CoTAPc–MWCNTs) were prepared using covalent immobilization of cobalt tetraaminophthalocyanine (CoTAPc) on them, and characterized by X-ray photoelectron spectroscopy, attenuated total reflection Fourier transform infrared spectra and thermogravimetric analysis. The oxidative decoloration of rhodamine 6G (Rh6G)...
A method for preparing protective titanium carbide (TiC) coatings on carbon fibres has been developed using a molten salt synthesis method. The TiC coatings were formed on the surface of carbon fibres in a reaction medium consisting of Ti powder in a mixture of molten LiCl–KCl–KF salts under an argon atmosphere at 900 and 950°C. The structure and morphology of the TiC coatings were characterized by...
