Synthesis of the first article platinum nanoparticles having excellent catalytic activity by a hydrothermal method, and further with a large specific surface area, high stability and high purity SWNTs carboxylated high catalytic activity of the reaction and, ultimately, a highly efficient catalytic activity the COOH-SWCNTs-PtNPs composites. Dispensing method of composite material supported on the glassy carbon electrode clean, can be efficiently prepared, rapid electrochemical sensor detects ethinyl estradiol molecule. The COOH-SWCNTs-PtNPs composites were not complexed with the detection result and the COOH-SWCNTs PtNPs comparison, found COOH-SWCNTs-PtNPs composite material having a higher electrocatalytic activity.

In this paper, the platinum nanoparticles with good catalytic activity are synthesized by hydrothermal method, and then further react with the high-purity single-wall carbon nanotubes with larger surface area, strong stability and high catalytic activity, and finally obtain the COOH-SWCNTs-PtNPs composite material with high catalytic activity. The composite material is loaded on to a clean glass carbon electrode by drip coating method to produce an electrochemical sensor that can detect the thylene alcohol molecule efficiently and quickly. The COOH-SWCNTs-PtNPs composite scanted with the non-composite PtNPs and COOH-SWCNTs respectively, and found that THE COOH-SWCNTs-PtNPs composite synth had higher electrocatalytic activity.

In this paper, platinum nanoparticles with good catalytic activity were synthesized by hydrothermal method, and then reacted with carboxylated single-walled carbon nanotubes with large specific surface area, strong stability and high catalytic activity. Finally, cooh-swcnts-ptnps composite with high catalytic activity was obtained. Using drop coating method, the composite material was loaded on a clean glassy carbon electrode to prepare an electrochemical sensor which can detect ethinylestradiol efficiently and rapidly. The cooh-swcnts-ptnps composite was compared with the uncomposite ptnps and cooh-swcnts respectively. It was found that cooh-swcnts-ptnps composite had higher electrocatalytic activity.
