•Novel poly-hydrogen cyanide nanofibers were prepared by directly heating the formamide.•Poly-hydrogen cyanide nanofibers have a diameter of 100–250 nm and length of 1–2 μm.•The structure of poly-hydrogen cyanide nanofibers is confirmed (HCN)x polymer.•Poly-hydrogen cyanide nanofibers exhibit much more efficiency by degradation of methyl orange than N-TiO2 under visible light irradiation.
Poly-hydrogen cyanide (PHC) nanofibers were prepared by directly heating the formamide (HCONH2) in a stainless-steel autoclave at 200 °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.
