Nanometer porous silver alloy material and preparation method thereof

Nanometer porous silver alloy material and preparation method thereof

The invention discloses a nanometer porous silver alloy material and a preparation method thereof. Specifically, amorphous alloy is taken as a precursor; elements, excluding noble metals such as Ag, Pt, Pd,Au, Ru, Rh, Os and Ir in the alloy, are corroded by a dealloying method to form a nanometer po...

description The invention discloses a nanometer porous silver alloy material and a preparation method thereof. Specifically, amorphous alloy is taken as a precursor; elements, excluding noble metals such as Ag, Pt, Pd,Au, Ru, Rh, Os and Ir in the alloy, are corroded by a dealloying method to form a nanometer porous structure; a lace is elemental silver or silver alloy (a solid solution, the solute atom is noble metals such as Pt, Pd, Au, Ru, Rh, Os and Ir); the feature size of both the pores and the lace is smaller than 50 nanometers. The nanometer porous silver alloy material prepared by the method disclosed by the invention has self-sustaining property and structural controllability and can maintain the structural integrity and self-sustaining property after 70% of mass is lost. The preparation method and a detection method are simple; the obtained material can be widely applied to various catalytic reactions.
