Psi substrate was synthesized by Photo-electrochemical etching (PECE) with a laser power density (15 mW/cm2), monometallic structure has been synthesized by dipping fresh Psi sample in salt solutions (AgNO3 and PdCl2) for about 5 min, while bimetallic nanoparticles was synthesized by dipping Psi in mix solution at a ratio (1:1) for about 2 and 4 min. The monometallic and bimetallic nanoparticles were confirmed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDS). The results show that the composition of Ag@Pd alloy nanoparticles was uniformly dispersed and well-defined distribution on Psi surface; having an average size of (8 to 7.1) nm is smaller than monometallic nanoparticles sizes. The lower Ag@PdNPs size and therefore a higher specific surface area (S.S.A) were obtained for about (71 to 63.8) m2/gm, these high specific area is most important for different application such as: chemicals or gas sensing. 2018-12-25T06:34:28Z 2018-12-25T06:34:28Z 2018-10 Article International Journal of Nanoelectronics and Materials, vol.11(4), 2018, pages 461-472 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/57743 http://ijneam.unimap.edu.my en Universiti Malaysia Perlis (UniMAP)
