Pulsed laser ablation (PLA) in a liquid is the unique method of preparation of pure nanocolloids and ultrafine powders on their basis [1]. PLA of chemically active metals allows one to initiate a large number of chemical reactions and to influence effectively on the structure and composition of the prepared nanoparticles (NP) [2, 3]. Aluminum with electrochemical potential of 1.7 V belongs to these metals. The NP of various compositions were prepared by ablation with variable solvents, including addition of precursors, at different laser radiation wavelengths [4–6]. For a number of fundamental and applied problems, of interest are nanodispersed materials based on aluminum without impurities characteristic for their chemical synthesis, in particular, Al(OH)3 for use in medicine as sorbents and γ-Al2O3 for use in catalysts. The purpose of the present work is preparation of pure aluminum oxide and hydroxide nanoparticles by the method of pulsed laser ablation and their subsequent characterization.
