摘要: Abstract Halloysite is a very interesting naturally occurring aluminosilicate, which has received great attention due to its nanotube shape. We used this nanostructured material as support for hematin, biomimetic catalyst, was successfully employed the aniline polymerization. The adsorption of hematin (Heme) on halloysite nanotubes (HNTs) confirmed by UV–vis spectroscopy, zeta potential measurements, thermal analysis and X-ray diffraction. resulting HNTs/Heme/PANi nanocomposites were characterized transmission electron microscopy (TEM) Fourier transform infrared spectroscopy (FTIR). FTIR formation conjugated form polyaniline (PANi). Electrical conductivity in order 8.8 × 10 −1 S/cm. This work shows use catalyst immobilization, opening possibilities large-scale environmentally friendly synthesis.
