In this work we described the optical study of palladium nanoparticles containing 4.7 and 10wt.% in metallic form supported in magnesium oxalate. Their mean diameter is 2 nm. The nanoscale of the palladium particles allows for the interesting study of the nonlinear response of these medium under optical stimuli. An investigation of the nonlinear properties of the pre-catalyst Pd(OAc)2 in methanol solution and a micelle medium by the Z-scan technique in a millisecond time scale has allowed the evaluation of the values of the nonlinear refractive index in the thermal origin. Preliminary results show that a nonlinear refractive index of the palladium nanoparticles in micellar systems is greater than in methanol solution, probably due to the reduction process from the oxidation state (II) to (0) in methanol medium. The comparison of the differences between species of palladium in the oxidation states (II) and (0) is under investigation.
