The Au@Rh core–shell nanoparticles (NPs) with Rh depositing on the spherical Au NPs were synthesized for the first time using successive reduction method. Au NPs were prepared by reducing HAuCl 4 with l-ascorbic acid as the reducing agent and cetyltrimethylammonium bromide (CTAB) as the capping agent. Au@Rh NPs were then obtained by reducing RhCl 3 in the presence of the pre-synthesized...
Novel chain-like CoNi alloy microstructures have been successfully prepared via a solvothermal route at 155°C with the assistance of polyvinylpyrrolidone (PVP) as a growth directing agent. The resulting samples were characterized by XRD, SEM, and VSM techniques. The effects of synthetic parameters including PVP dosage and reaction time on the morphologies of the obtained CoNi were investigated in...
