PALLADIUM NANOPARTICLE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/045433
Kind Code:
A1
Abstract:
A palladium nanoparticle and a preparation method therefor. The preparation method includes the following steps: formulating a mixed solution containing a cobalt salt and a stabilizer, and introducing a protective gas into the mixed solution for deoxygenization; under the protective gas atmosphere, keeping the deoxygenated mixed solution at a temperature of 100°C and stirring for 5 min-10 min, then adding a sodium borohydride solution according to the molar ratio of 10-20 : 1 of sodium borohydride to the cobalt salt, after a sufficient reaction, adding a palladium salt solution according to the molar ratio of 1 : 1-1.5 of the palladium salt to the cobalt salt, then keeping same at a temperature of 100°C and under the protective gas atmosphere, and continuously stirring until a complete reaction; and filtering the reaction solution, retaining the filter residue, washing and drying the filter residue to obtain the palladium nanoparticle. This palladium nanoparticle is of a hollow shell structure which is a porous structure, and has a higher specific surface area with respect to a traditional palladium nanoparticle.
