摘要

利用银纳米粒子电化学置换钯离子的方法合成了Ag(Pd)双金属纳米结构（Ag(Pd)NPs）。根据对扫描电子显微镜、能量色散 X 射线显微分析和 X 射线粉末衍射结果的比较分析，确定所获得的 Ag(Pd)NPs 可视为 "核壳 "纳米系统，其中核为银，壳为尺寸为 5-15 纳米的钯纳米粒子。研究将 Ag(Pd)NPs 作为催化剂用于苯甲醇的有氧液相氧化。在反应体系中加入 Ag(Pd)NPs 可使反应速度加快 14 倍。

Synthesis and Catalytic Properties of Ag(Pd) Bimetallic Nanoparticles

Ag(Pd) bimetallic nanostructures (Ag(Pd)NPs) were synthesized using the galvanic replacement of palladium ions with silver nanoparticles. Based on a comparative analysis of the results of scanning electron microscopy, energy dispersive X-ray microanalysis, and X-ray powder diffraction, it was established that the obtained Ag(Pd)NPs can be considered as “core-shell” nanosystems, in which the core is silver, and the shells are palladium nanoparticles with a size of 5–15 nm. Ag(Pd)NPs were studied as catalysts for the aerobic liquid-phase oxidation of benzyl alcohol. The addition of Ag(Pd)NPs to the reaction system accelerates the reaction in 14 times.
