| 摘 要： | 采用酒石酸铜前驱体热分解得到纳米铜粒子作为催化剂,分别对250℃、280℃、310℃分解产生的纳米铜粒子进行测试分析,在3个温度下用化学气相沉积法生长螺旋纳米碳纤维并进行综合热分析。采用X-射线衍射(XRD)分析其物相组成,晶粒大小;用扫描电子显微镜(SEM)观察螺旋纳米纤维的外观形貌。结果表明,310℃生长出的螺旋纳米碳纤维纯度高、外观形貌清晰,热分析质量损失少。

| Abstract: | This experiment adopted the cupric tartrate precursor body decomposed copper nanop articles as a catalyst,respectively, 250 ℃, 280 ℃ ,310 ℃ to test copper nanoparticles produced by the decomposition analysis. At three temperalures growed helical carbon nanofibers with chemical vapor deposition method and carried on comprehensive thermal analysis. Using XRD analyed the phase composition and grain size. The appearance of the helical carbon nanofibers morphology was observated by SEM observation. Results showed that the growth of 310 ℃ helical carbon nanofibers have high puri- ty, clear appearance morphology, less thermal analysis of quality loss. |
