Our paper "The average particle diameter calculated from TEM image analysis was found to be inversely proportional with the duration of the oxidation in nitric acid. Crystallite sizes determined from XRD patterns confirmed this general tendency. These results are expected be useful in improving the reproducibility of carbon nanotube based heterogeneous catalysts. Moreover, the findings will also help us in designing the pore wall chemistry of our porous nano composite materials.
