Abstract:

In this study, a simple Physical Vapor Deposition (PVD) process called the Horizontal Vapor Phase Growth (HVPG) Method was used to grow carbon nanomaterials from two different activated carbon powder, one is an industrial grade activated carbon and another is labeled as PUREBLACK 205 Carbon. The source material was weighed to 0.035 grams and placed in a sealed quartz tube. The quartz tube was the set in a programmable tube furnace and set to temperatures of 1200°C,1000°C, 800°C and 600°C with dwell time of 4 to 8 hours with 2 hours increment for the PUREBLACK 205 Carbon and 8 hours for the industrial grade activated carbon. Scanning Electron Microscopy revealed that the carbon nanomaterials with rod-like structure grew under high vacuum conditions (~10-6 Torr) with a growth temperature of 1200°C for 8 hours using the industrial grade activated carbon. On the other hand, nanowires were found using the PUREBLACK 205 Carbon with high vacuum conditions of approximately 10-6 Torr with a growth temperature of 1200°C for 6 hours. Energy Dispersive X-ray revealed the elemental composition of the nanorods as Carbon (60.05%) and Silicon (49.95%). The nanowires, on the other hand, were made up of Carbon (41.85%), Oxygen (31.53%) and Silicon (26.61%).
