Abstract

In this paper, a novel approach in modifying the properties of hybrid structure of silver nanoparticle (AgNPs)/porous silicon (PSi) is carried out through deposition of multi wall carbon nanotubes (MWCNT); on PSi surface. The PSi layer is prepared by Photo-electrochemical etching technique using different current densities (15, 20, 25 and 30 mA/cm2). The AgNPs/ MWCNT is deposited on the PSi surface by a simple ion reduction process using aqueous solutions of silver salt (AgNO3) at 5 10-2 M, 10-2 M, 10-3 M, and 10-4 M concentrations. Structural, morphological and optical characterizations of (AgNPs/MWCNT/PSi) hybrid structures are analyzed in respect to the PSi layer morphology. The obtained results showed strong possibility of effectively controlling the morphological and structural properties of hybrid structure by controlling the pores’ diameters. The deposition of the MWCNT and AgNPs on the walls and pores of the PSi structure enhanced the surface morphology of hybrid structure in addition to its specific surface area (S.S.A). The incorporating of MWCNT on the PSi substrate produced at 25 mA/cm2 current density and 5 10-2 M AgNO3 concentration led to higher specific surface area (S.S.A).
