METHOD FOR PRODUCING POLYMER CARBON NITRIDE IN NANOSHEETS

METHOD FOR PRODUCING POLYMER CARBON NITRIDE IN NANOSHEETS

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...

Zusammenfassung: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.
