Our laboratories are located in the University of Oklahoma's Sarkey´s Energy Center, which is the largest and tallest building on campus. This complex has 340,000 square feet (32,000 m2) of office space, underground laboratories, and storage rooms. Sarkey´s Energy Center houses several academic units including the College of Earth and Energy, and the Chemical, Biological and Materials Engineering.
We count with three different laboratories where SWNT production and characterization, catalytic activity tests, and catalyst synthesis are performed as part of our research in catalytic science. For more information, follow any of these links:
The role of water in carbon feed on the surface-guided growth of horizontally aligned single-walled carbon
nanotubes (HA-SWCNTs) was investigated. It is shown that the amount of water can be optimized to favor HA-SWCNT growth, which is proposed to be due to selective etching of carbon deposits at carbon–metal interface. Without water, nanotube–nanotube interaction and carbon accumulation at the interface are disproportionately large compared to the rate of nanotube growth, leading to catalyst deactivation. With excess water, suppression of nanotube growth occurs, resulting in reduced carbon yield on the surface.
Intermediate carbon/water feed ratios achieve cleaner growth with high efficiency.
