Embodiment 1
[0033] Preparation of Carbon Nitride Nanotubes (CNTs)
[0034] Weigh 1.0 g of melamine and disperse it into 70 mL of deionized water, heat and stir in an oil bath at 80°C until the melamine is completely dissolved. The obtained transparent solution was transferred to a hydrothermal kettle, and the hydrothermal kettle was heated in an oven at 200° C. for 10 h. After it naturally dropped to room temperature, the obtained sample was washed with water and absolute ethanol three times, and dried to obtain melamine nanorods. The melamine nanorods were placed in a porcelain ark, raised to 550°C at a rate of 2.5°C / min in a muffle furnace and held for 4 hours. After the calcination process, it was naturally cooled to room temperature, the obtained yellow sample was fully ground, washed with water three times, and dried in a vacuum oven at 60°C.
