EXAMPLE - Multi-wall carbon nanotubes (0.3 g) were put into a round four-neck flask reactor (500 ml), and then ethylene glycol (280 ml) was added to form first mixture. The first mixture was stirred for 30 minutes, and then the round four-neck flask reactor was put into an ultrasonic cleaner to disperse carbon nanotubes in ethylene glycol using ultrasonic waves for 3 hours. In this case, the temperature of the four-neck flask reactor must not exceed 50 degrees C. After the ultrasonic treatment, the round four-neck flask reactor was mounted with a stirrer and was connected with a thermometer and a condenser for cooling. Subsequently, polyvinyl pyrrolidone (1.68 g) and oleylamine (2.8 ml) were put into the round four neck flask reactor, and platinum acetylacetonate (0.259 g) was put into it to form a second mixture. A vacuum pump was connected to the reactor to remove air from the reactor and to substitute air with nitrogen. When nitrogen was continuously introduced, nitrogen was discharged out of the reactor, thus preventing oxygen from flowing into the reactor. A mantle was provided under a flask, and the second mixture was stirred at 400 rpm for 30 minutes. Subsequently, the reactor was heated to 200 degrees C for 40 minutes to react the second mixture for 1 hour. After the reaction was completed, the reactor was slowly cooled to room temperature for 3 hours to form a carbon nanotube-platinum composite.
