ABSTRACT
An overview of recent developments in the synthesis of aluminum nanoparticles (Al NPs) and their applications in the field of energetic materials is presented. Various methods of preparing the Al NPs of different sizes including physical (laser ablation) and chemical methods are highlighted. Some of the results obtained by our group on the passivation of the Al NPs are highlighted. The laser ablation in liquids technique with ultrashort (picosecond and femtosecond) laser pulses is a green technique for preparing Al NPs devoid of any precursors, whereas the chemicals method yields passivated Al NPs. Among the various applications of the Al NPs, energetic applications are discussed in detail. This article is concluded by emphasizing the prospects of Al NPs in various energetic applications and the future of different techniques to synthesize them.
