Photocatalytic activities of carbon nanocapsules encircled by nickel nanoparticle composites to organic dyes degradation

Novel carbon nanocapsules encircled by nickel nanoparticle composites were prepared by the reaction of fullerene[C-60] and nickel hydroxide at 700 degrees C for 2 h. Carbon nanocapsules encircled by nickel nanoparticle composites were characterized by X-ray diffraction, Raman spectroscopy, scanning electron microscopy and transmission electron microscopy. It may be confirmed the structure of fullerene[C-60] changed into capsule like type of carbon nanomaterials and nickel nanoparticles were surrounded by carbon nanocapsules by HR-TEM. Application of carbon nanocapsules encircled by nickel nanoparticle composites could be used as a photocatalyst in the degradation of organic dyes under ultraviolet light at 254 nm.
