Method for catalyzing rapid spontaneous combustion of N (CN) 2-IL-H2O2 system by Cu (I)-MOF

Abstract

The invention provides a method for catalyzing rapid spontaneous combustion of an N (CN) 2-IL-H2O2 system by Cu (I)-MOF, belongs to the field of rocket propellants, and aims to solve the problem that the N (CN) 2-IL-H2O2 system does not spontaneously ignite. The preparation method comprises the following steps: mixing twin-crystal Cu (I)-MOF and N (CN) 2-IL ionic liquid, dripping the obtained mixed fuel into a cylindrical open glass bottle oxidant pool containing H2O2, and testing ignition delay time. The electron microenvironment of the Cu center in Cu (I)-MOF is adjusted by using the substituent group of the ligand, so that the d-band center is closer to the Fermi level, H2O2 is more easily activated, and the ignition delay time is as low as 18.5 ms. The method is easy to operate and rapid in reaction, low ignition delay time can be obtained, and a foundation is laid for actual application of the IL-H2O2 serving as a green spontaneous combustion propellant through precise synthesis of Cu (I)-MOF.
