摘要
A novel nano-cobalt/ethanol sol was firstly obtained by pulsed laser ablation on the interface of solid and flowing-liquid. TEM results show that nano-cobalt particles size is about 30 nm. Electronic diffraction and XRD analysis both indicate that the nano-cobalt is non-crystalline. It was found that the stretching vibration of associating hydroxyl(γ OH) and the deformation vibration of C-H in ethanol are strengthened, but stretching vibration of γ C-O in primary hydroxyl of ethanol is restrained through the FTIR spectrum. The UV-Vis results show that there are one strong absorption peak at 231 99 nm due to primary nano-cobalt particles and two medium absorption peaks at 273 00 and 308 56 nm due to quantum confine effect.
