摘要Ni-deposited SiC particles are prepared successfully by a facile chemical reaction approach. The structure and morphology analyses demonstrate the Ni nanoparticles have been deposited on the surface of SiC particles. The deposition behavior of Ni on the surface of SiC particles is investigated. Pd-Sn catalytic nuclei formed in the pretreatment process promote the redox reaction and lead to the reduction of Ni2+ to metal nickel. Moreover, the kinetic mechanism of the reaction process of Ni2+ and has also been discussed in detail. Kinetic models have been established.
