Capping and passivation of aluminum nanoparticles using alkyl-substituted epoxides

摘要

Although there are many applications for nanoscale aluminium materials, there are challenges with producing air-stable nanoscale aluminium structures with small diameters (<100nm). Aluminium nanoparticles react with oxygen and water to produce Al2O3 to give a 2-6nm-thick oxide layer. For nanoparticles with diameters of less than 20nm, the oxide layer can account for more than 70% of the particle mass.
