Influence of Growth Conditions on the Formation of Fish-Bone GNFs by CVD Using Ni Foam as Catalyst

GNFs with fish-bone structure were first produced by a simple method. To optimize the growth conditions, different hydrogen treatment of the catalyst, different growth time and growth temperature, as well as different gas flow rate were employed. The effects of these growth conditions on the morphology and yield of GNFs were studied in details. It is found that fish-bone GNFs with high yield and high purity can be produced under the optimized conditions.
