Mild Hydrothermal Synthesis of Ni–Cu Nanoparticles

Mild Hydrothermal Synthesis of Ni–Cu Nanoparticles

Magnetic Ni-rich Ni–Cu nanoparticles with Ni : Cu mass ratio (S) of 2.0 and 2.6 were prepared using a mixture of polyoxyethylene (10) isooctylphenyl ether (Triton X-100) and sodium dodecyl sulfate (SDS) in a mild hydrothermal condition at 95ºC. X-ray diffractometry (XRD) showed that the nanoparticle...

X-ray diffractometry (XRD) showed that the nanoparticles prepared at S=2.0 possessed Ni–Cu alloy characteristic whereas the characteristic was absent at S=2.6.
