ساخت نانوذرات Pd/MoO3-x با ترکیب روش کندوسوز لیزری مولیبدن در محیط مایع و احیای خودبخودی پالادیم

In this paper successive method involving laser ablation followed by autocatalytic reduction has been developed for fabrication of pd-moo3-x. first molybdenum oxide nanoparticles were prepared by laser ablation in h2o or h2o2 liquid using excimer (krf, ?=248 nm) or solid state (nd:yag, ?=1064 nm) lasers. then pdcl2 solution with different concentrations were added to the colloidal solution with the hope palladium nanoparticles are deposited upon the initial nanoparticles. the effect of laser wavelength on palladium solution and ablation environment were studied by means of transmission electron microscopy (tem), uv-vis spectrophotometry and atomic force microscopy (afm).
