Glucose stabilized magnetic palladium nanoparticles exhibiting enhanced magnetic properties under exposure to hydrogen

H2[PdII(Cl)4] and [PdIV(NH3)4Cl2]Cl2 as starting materials produce palladium nanoparticles (Pd NPs) using hydroxylamine as reducing agent in aquous solvent in the presence of D-glucose as stabiliser and capping agent. Pd NPs with average 6 nm size was isolated from Pd(II) complex whereas the average Pd NPs of 8 nm was produced from Pd(IV) under similar reaction condition. These Pd NPs are characterized by UV–Vis, FT-IR, XRD, TEM and SEM and EDX studies. Magnetism of 6 nm sized Pd NPs show enhanced ferromagnetic behavior compared to those from 8 nm sized Pd NPs. On hydrogen exposure smaller sized Pd NPs show an increase in magnetization
