Synthesis, Characterization and Gas Sensor Application of New Composite Based on MWCNTs:CoPc:Metal Oxide

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 (60%Ni3O4 40%-Co3O4 ) have been functionalized with multiwall carbon nanotubes (F-MWCNTs) to produce (F-MWCNTs/MO) nanocomposite (E2) and mixed CoPc yield (F-MWCNT/CoPc/MO) (E3). These composites were investigated different analytical spectrophotometric methods such as 1H-NMR (0-18 ppm), FTIR spectroscopy in the range (400-4000cm-1), powder X-rays diffraction (PXRD, 2θ o = 10-80), Raman (0-4000 cm-1), UV-Visible spectrophotometry (0-800 nm). Then activity these a gas sensing (Ammonia, Methanol Acetone). For each case, 0.2 mg/.mL prepared Copc, Copc/MWCNT, Copc/MWCNTs–MO dispersed 1m ammonia, methanol acetone at 298K. surface morphology heterogeneous.
