Abstract
The synthesis of new substituted cobalt Phthalocyanine (CoPc) was carried out using starting materials Naphthalene-1,4,5, tetracarbonic acid dianhydride (NDI) employing dry process method. Metal oxides (MO) alloy of (60%Ni3O4 40%-Co3O4 ) have been functionalized with multiwall carbon nanotubes (F-MWCNTs) to produce (F-MWCNTs/MO) nanocomposite (E2) and mixed with CoPc to yield (F-MWCNT/CoPc/MO) (E3). These composites were investigated using different analytical and spectrophotometric methods such as 1H-NMR (0-18 ppm), FTIR spectroscopy in the range of (400-4000cm-1), powder X-rays diffraction (PXRD, 2θ o = 10-80), Raman spectroscopy (0-4000 cm-1), and UV-Visible spectrophotometry (0-800 nm). Then the activity of these materials was investigated as a gas sensing of (Ammonia, Methanol and Acetone). For each case, 0.2 mg/.mL of the prepared Copc, Copc/MWCNT, Copc/MWCNTs–MO was dispersed in 1m of ammonia, methanol and acetone at 298K. The surface morphology of the prepared materials was heterogeneous.
Highlights
Multiwall carbon nanotubes (MWCNTs) were discovered in 1991 as a secondary product of fullerene preparation [1]
Carbon Nano Tubes are insoluble in all solvents due to solid Van-Der-Waals intelligent that firmly holds them, but chemical functionalization of Carbon nanotubes (CNTs) may improve dissolvability in different solvents and to create novel hybrid materials possibly appropriate for diverse applications such as Catalysts, Sensors, Transistors, Membranes, Electrodes, Solar cells and Fuel cells [7]
The present study describes the preparation of cobalt phthalocyanine (CoPc) and its combination as nanocomposites materials to yield (Copc/F-MWCNTs/ Ni3O4-Co3O4)
Summary
Multiwall carbon nanotubes (MWCNTs) were discovered in 1991 as a secondary product of fullerene preparation [1]. The tube walls are made up of a hexagonal grid of carbon molecules resembling closely to the atomic planes of graphite [4]. Carbon nanotubes (CNTs) are characterized as a cylinder in three dimensions content of carbon atoms, and have hybridization sp which is stronger than diamond with hybridization sp3 [5]. Carbon Nano Tubes are insoluble in all solvents due to solid Van-Der-Waals intelligent that firmly holds them, but chemical functionalization of CNTs may improve dissolvability in different solvents and to create novel hybrid materials possibly appropriate for diverse applications such as Catalysts, Sensors, Transistors, Membranes, Electrodes, Solar cells and Fuel cells [7]. Metal Free Phthalocyanines (H2Pc) is an organic compound with the formula (C8H4N2)4H2. It was discovered in 1907 by Braun and Tcherniac [9]. Phthalocyanine (PC,1) (tetrabenzo tetraazo porphyrin) compounds are thermally stable and has good catalytic performance [10]
