Multiwalled carbon nanotubes filled with MgO nanorods were synthesized through the reaction of ethanol and Mg powder in the presence ofTiO2at 400C°. X-ray powder diffraction indicated that the sample was composed of graphite and cubic MgO. Transmission electron microscopy studies showed that multi-walled CNTs with the outer diameters of 70–130 nm were filled with discontinuous MgO nanorods whose diameter was in the range of 25–40 nm. The ratios of the band intensities(ID/IG=0.67)in Raman spectrum implied that carbon nanotubes had good crystallinity. The influence of correlative reaction factors on the morphology of the sample and the possible formation mechanism were discussed.

Magnetic Multiwalled Carbon Nanotubes

A disposable, magnetism-controlled, and amperometric immunosensor was fabricated for the determination of C reactive protein (CRP). Firstly, Fe3O4 (core)/Au (shell) nanoparticle (GMP)–coated multiwalled carbon nanotubes (MWCNT–GMP) were prepared. Then, monoclonal antibody (anti-CRP) was immobilized on MWCNT–GMP to prepare MWCNT–GMP/anti-CRP composite magnetic probes. At last, the probes was adsorbed on the surface of N,N''-bis-(2-hydroxy-methylene)-o-phenylenediamine cobalt (CoRb) modified, screen-printed carbon electrodes through external magnetic field.The amount of CRP in the serum sample was determined by one-step immunoassay. When different concentrations of CRP were added into25μL of phosphate-buffered solution (pH7.0) containing10-4M H2O2, the percentage of DPV cathodic peak current decrease (CR%) exhibited a linear relationship with the concentration of CRP in the range of 0.3–100 μg L-1.The detection limit was 0.16 μg L-1(3б).The immunosensor was used to determine CRP in serum samples of patients with heart diseases, and the results were consistent with those of the traditional ELISA method. The proposed amperometric immunosensor was sensitive, rapid, magnetic field–controlled, and disposable; therefore, it could be used to determine even traces of CRP in the blood serums of patients with heart diseases.

Iron tetrapyrazinoporphyrazine (FePTpz) and cobalt tetrapyrazinoporphyrazines (CoPTpz) supported on multiwalled carbon nanotubes (MWCNTs) are prepared by solid phase synthesis method. The products are characterized by scanning and transmission electron microscopy. The electrocatalytic activity of the obtained MWCNTs-supported FePTpz and CoPTpz assemblies (MPTpz/MWCNTs) is measured by cyclic voltammetry and rotating disk electrode techniques in an oxygen-saturated 0.1M KOH. The results show that MPTpz/MWCNTs are more efficient than reference MPTpz. FePTpz/MWCNTs are more efficient for O2 reduction than CoPTpz/MWCNTs, both of FePTpz/MWCNTs and CoPTpz/MWCNTs exhibit a one-step, four-electron pathway for ORR.
