Nanothermites are a class energetic material containing both fuel and oxidizer which undergo a very rapid redox reaction and release energy in a fast manner. In most formulations, aluminum(Al) was preferred fuel because of its abundance and high calorific value, and the oxidizer, such as Bi 2 O 3 , CuO, Fe 2 O 3 , M o O 3 , were generally used in the reactions. Compared with conventional EMS (energetic materials), Nanothermites demonstrate higher reaction rate and higher energy density due to reducing the diffusion distance between fuel and oxidizer.
