Core-shell hybrid nanomaterial based on prussian blue and surface active maghemite nanoparticles as stable electrocatalyst
Original language description
A novelcore-shell nanomaterial based on prussian blue(PB) coating on peculiar surface active maghemite nanoparticles SAMNs) ,was developed.The synthetic process involves the direct crystallization of Fe(II)(CN)6 4 onto the surface of SAMNs by simple incubation in water at controlled pH,demonstrating the presence of under-coordinated Fe(III)on nanoparticle surface.The coating reaction occurs in a narrow pH range and the synthetic procedure was optimized.The resulting SAMN@PB hybrid nanostructures were characterized by transmission an dscanning electron microscopy,Mössbauer,UV-vis and FTIR spectroscopy and X-powder diffraction.The nanomaterial,characterized by high stability in alkaline media,behave as excellent electro-catalyst for hydrogen peroxide reduction.The stability of SAMN@PB hybrid has been investigated as a function of pH,showing excellent stability up to pH 9.0 and demonstrating the feasibility of SAMNs,superficially derivatized with prussian blue,to produce an efficient and
