Preparation of MXene-Cu2O nanocomposite and effect on thermal decomposition of ammonium perchlorate

• MXene-Cu2O nanocomposite has been synthesized firstly.
• Cu2O heterogeneous nucleate and grow on the surface of MXene directly.
• The thermal decomposition of AP was studied with different samples.
• MXene-Cu2O has a great influence on the thermal decomposition of AP than that of pure MXene and Cu2O.

MXenes are novel graphene-like 2-D materials. Cu2O is an effective additive for thermal decomposition of ammonium perchlorate (AP). We reported the synthesis of MXene (Ti3C2), Cu2O and MXene-Cu2O respectively. The samples were characterized by means of X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). Results indicate that the MXene is composed of lots of nano-sheets and the thickness is 30 ± 10 nm, and Cu2O nanoparticles nucleate and grow heterogeneously directly on the surface of MXene. The effect of these MXene, Cu2O and MXene-Cu2O samples on the thermal decomposition of AP were investigated using TG-DSC. The results revealed that MXene-Cu2O have a great influence on the thermal decomposition of AP than that of pure MXene and Cu2O.
