palladium nanoparticles synthesis using polymeric matrix: poly(ethyleneglycol) molecular weight and palladium concentration effects

due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple andlow cost method is very important. in this work, pd nanoparticles were synthesized with narrow sizedistribution by loading metal salt (pd(oac)2 ) into the polymeric matrix (peg) as reducing agent andstabilizer. also, the effect of metal salt concentration and peg molecular weight on the conversion ofpd 2+ to nano pd 0 and synthesized palladium nanoparticles morphology were investigated by uv-visspectroscopy, xrd and tem. the uv results confirmed the significant effect of peg molecular weighton the reduction reactivity of polymeric matrix. also, tem and xrd results revealed that metal saltconcentration has significant effect on the synthesized pd nanoparticles size.
