文摘

Poly-hydrogen cyanide (PHC) nanofibers were prepared by directly heating the formamide (HCONH₂) in a stainless-steel autoclave at 200 掳C. The composition and structure of the products were characterized by X-ray diffraction, transmission electron microscopy, UV-vis diffuse reflectance spectrum, thermogravimetric analysis, Fourier transform IR, Raman and X-ray photoelectron spectroscopy. The results showed that the as-prepared nanofibers are graphite-like structure C/N ratio of 1.23. The as-prepared nanofibers exhibited higher photocatalytic activities by degradation of methyl orange (MO) than N-TiO₂ under visible light irradiation.
