Deposition of silver nanoparticles on montmorillonite platelets by chemical plating
A method for directional deposition of silver nanoparticles on montmorillonite platelets was developed. In order to utilize the elemental layer sheets of montmorillonite as substrate for chemical plating, the clay was modified with dodecyl benzyl dimethyl ammonium chloride, and then exfoliated in toluene with the aid of ultrasonic. Silver deposition in dimethyl formamide with PVP as stabilizer was nucleated at the montmorillonite surface and in the solution. Directional deposition was successful through sensitization with stannous isooctoate and reduction of silver nitrate with Tin(II) ions.
