Nanosilver porous material particles and fabricating method thereof

Abstract

Nanosilver porous material particles and method for manufacturing the same are disclosed. The nanosilver porous material particles include nanosilver particles distributed on the surface thereof. First, a nanosilver precursor is dissolved in water and a proper quantity of a fixation agent is added to form a solution. Next, a proper quantity of the porous material particles is added into the solution and that is mixed well to form a suspension. Next, the suspension is allowed to stand for a predetermined period of time, and then the suspension is filtered to separate the porous material particles from the solution. Finally, the resulting porous material particles are baked and dried.

1 . A nanosilver porous material particle, comprising:
 a porous material particle; and   a plurality of nanosilver particles homogeneously distributed on a surface of said porous material particle.   
     
     
         2 . The nanosilver porous material particle according to  claim 1 , wherein said porous material particle is made by ceramic, activated carbon, hollow centered glass ball, bamboo carbon, coconut shell carbon, charcoal, Tenax-TA, which is composed by 2,6-diphenyleneoxide, or a composite thereof. 
     
     
         3 . The nanosilver porous material particle according to  claim 2 , wherein said activated carbon is in the form of powder, particle-pellet, fiber, pillar-shaped or honeycomb-shaped particle.
