摘要：

The temperature-programmed ammonia desorption, IR spectroscopy, differential thermal analysis, and inorganic test-reagent methods were used to study the properties of copper nanopowders prepared under various conditions of wire electroexplosion and gas-phase synthesis. Electroexplosion in nitrogen was shown to favor the formation of copper nanopowders with acid surface properties. Explosion in argon produced powders with reducing surface properties, which could be detected in aqueous solutions of ammonia and iodine during several minutes.
