The invention discloses a method for preparing a
carbon nitride nanoribbon and a secondary
assembly structure of the
carbon nitride nanoribbon. The method for preparing the
carbon nitride nanoribbon comprises the following steps: (1) preparing materials; (2) heating; (3) separating; (4)
drying. The invention also provides a method for preparing the secondary
assembly structure of the carbon
nitride nanoribbon. The method is simple in process and low in cost, and the used template is a
sodium chloride crystal and can be easily dissolved and removed by water; the obtained nanoribbon is large in specific surface area, high in water
solubility and good in stability, and the
aqueous solution can be stabilized for over 15 days; moreover, according to the obtained nanoribbon, different secondary
assembly structures, such as micro-ribbons, microrods, microtubes, bouquets and ball-flowers, are easily obtained by utilizing different alcohols, and the obtained higher structure has wider application in the fields of environment conservation, energy, national defense and
chemical industry.
