METHOD FOR PRODUCING POLYMER CARBON NITRIDE IN NANOSHEETS

摘要

The invention relates to an industrially scalable production method for producing polymer carbon nitride formed by units of formula C 6 N 7 (NH)(NH 2 ) in a solid phase, comprising: a) the production of a solid mixture comprising a carbon nitride precursor having at least one acid-base catalyst; and b) the treatment of the mixture obtained in step a) at between 400°C and 800°C in an inert gas atmosphere, step b) being carried out in a closed system when the inner pressure of the system is between a threshold input pressure ( p ei ) and a threshold output pressure ( p si ), and in an open system when the inner pressure is outside the mentioned interval. Step b) is carried out in a thermal reactor which allows, by means of at least one valve, the inflow or outflow of gases according to the inner pressure.
