Electrochemical method for synthesizing metal-containing particles and other objects

摘要

The invention is directed to a method for producing metal-containing (e.g., non-oxide, oxide, or elemental) nano-objects, which may be nanoparticles or nanowires, the method comprising contacting an aqueous solution comprising a metal salt and water with an electrically powered electrode to form said metal-containing nano-objects dislodged from the electrode, wherein said electrode possesses a nanotextured surface that functions to confine the particle growth process to form said metal-containing nano-objects. The invention is also directed to the resulting metal-containing compositions as well as devices in which they are incorporated.

主权项

1. A method for producing metal-containing nano-objects, the method comprising contacting an aqueous solution comprising a metal salt and water with an electrically powered electrode to form said metal-containing nano-objects, wherein said electrode possesses a nanotextured surface having conductive nanoscopic projections pointed outwardly from the surface that function as nucleation sites and confine the particle growth process while permitting dislodging of said metal-containing nano-objects from the electrode.
