Title:
Pd-BASED COMPOSITE NANOPARTICLE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/041405
Kind Code:
A1
Abstract:
A Pd-based composite nanoparticle and a preparation method therefor. The preparation method comprises the following steps: preparing a mixed solution containing copper salt and a stabilizing agent; after the mixed solution is stirred for 5 to 10 minutes at room temperature, adding a reducing agent on the basis that the molar ratio of the reducing agent to copper ions is 1-100:1, and upon complete reaction, adding a palladium salt solution on the basis that the molar ratio of palladium salt to the copper salt is 1:5-50, and continuing stirring at room temperature until complete reaction is achieved; and filtering the reaction solution and then retaining the filter residue, and washing and drying the filter residue to obtain the Pd-modified Cu2O nanoparticle. In the Pd-modified Cu2O nanoparticle, Pd is deposited on the surface of the Cu2O nanoparticle with a mesoporous structure, so that the electron and mass transmission of the Pd-modified Cu2O nanoparticle is improved, the reactivity site of electrocatalysis is improved, and the Pd-modified Cu2O nanoparticle has higher electrocatalytical property than simple metal oxide nanomaterials.
