Covalent triazine framework enables uniform dispersion of Cu2O catalysts for effectively boosting thermal decomposition of ammonium perchlorate

In this study, an efficient strategy was proposed to provide a new insight for solving the problem of decreased catalytic effect and increased usage of transition metal oxides (TMOs) catalysts used for the thermal decomposition of ammonium perchlorate (AP), caused by the serious agglomeration. That is to realize the uniform dispersion of one typical TMO Cu 2 O on the surface of the covalent triazine framework (CTF) which has the features of nitrogen-rich, large specific surface area and special framework structure, based on the strong coordination interaction. Therefore, first of all, new CTF/Cu 2 O composites were successfully prepared, and the results on the morphology and structure characterization could show that the Cu 2 O was uniformly dispersed on the surface of CTF. Then, the CTF/Cu 2 O composites were found to obviously decrease the high temperature decomposition (HTD) peak of AP by 50 °C, showing the good catalytic effect of CTF/Cu 2 O composites and the feasibility of proposed strategy. Finally, the thermal decomposition process of AP was facilitated by the homogeneous dispersion of Cu 2 O on the surface of CTF and the large specific surface area of CTF that favored the adsorption of gas products during the decomposition process.
