    • 2O, Aldrich, 98%) 1-propanol solution was then mixed with the as-prepared sol-gel system (volume ratio 1:1). After 30 min of gelation, the sol-gel based catalyst was spin-coated onto a p-type silicon substrate followed by baking at 70 °C for 30 min. The resultant distribution of catalyst particle sizes was in the range of 10-30 nm after 700 °C high temperature annealing, as observed by SEM. Diamond nanowire growth was done in an atmospheric pressure chemical vapor deposition (CVD) chamber under isothermal conditions (900 °C). The ratio of methane to hydrogen flow was set at 500:100 standard cubic centimeters per minute (sccm) for 5 min and was then switched to 100:200 sccm for 25 min. After the standard nanotube process was completed, pure hydrogen was flowed through the quartz tube (2.5 cm wide and 1.4 m long) at 200 sccm without having pumped the methane from the chamber. The chamber was then slowly cooled over 12 h to ambient temperature.
