Preparation of Nano-Porous Silver by Electroless Plating

A preparation method of nanoporous silver was introduced. First, polystyrene (PS) was pretreated. Then silver was deposited on the surface of PS. And finally, PS was removed to obtain porous silver by extraction. The effects of different reaction conditions on the reaction rate and silver deposits were studied. The reaction conditions include silver nitrate concentration, sodium hydroxide concentration, glucose concentration and temperature. The best reaction condition is 0.074 molL−1 AgNO3, 0.22 molL−1 glucose, 0.05molL−1 NaOH and the reaction temperature is 20°C.
