Notes:
Monodispersed and nano-sized Ni powders were synthesized from aqueous Ni sulfatehexahydrate (NiSO4· 6H2O) inside sucrose as a nonionic polymer network by using wet chemicalreduction process. The influence of a nonionic polymer network on the particle size of the Ni powderswere characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM),transmission electron microscopy (TEM), and thermal gravimetric analysis (TGA). The Ni powdersobtained by adding of sucrose were nearly spherical in shape and seemed to be nano-sized, typically inthe range of 100 nm with not being agglomerated. As the sucrose content increased, the particle sizeof Ni powders steeply decreased and reached the minimum value, however, the particle size increasedagain with a further increase of sucrose content. This is believed to be due to the pore size of theswollen polymer network. As a result, the particle size of the Ni powders prepared by the reductioninside polymer network was strongly dependent of the sucrose content
