Bimetallic nanoparticles are attractive materials due to their novel electronic, magnetic optical and catalytic properties which are distinctly different from those of their monometallic counterparts. The nanoparticles are stabilised by the addition of a polar polymer, that binds to the surface of the nanoparticle. The final size, shape and morphology depends on a number of parameters, such as concentration of metal precursor, sodium borohydride to metal molar ratio, polymer to metal weight ratio and reduction time. A key component of this work, is to understand how the polymer binds to the metal surface. INS spectroscopy is well-suited to this task because the metal nanoparticle is essentially invisible to neutrons, only the organic layer will be visible.
