Abstract

The bimetallic Fe-Ru oxide nanoparticles were synthesized in the liquid-phase plasma (LPP) method which employed iron chloride and ruthenium chloride as precursors. The active species (OH·, Hα, Hβ, and O(I)) and the iron and ruthenium ions were observed in the plasma field created by the LPP process. The spherical-shaped bimetallic Fe-Ru oxide nanoparticles were synthesized by the LPP reaction, and the size of the particles was growing along with the progression of the LPP reaction. The synthesized bimetallic Fe-Ru oxide nanoparticles were comprised of Fe2O3, Fe3O4, RuO, and RuO2. Ruthenium had a higher reduction potential than iron and resulted in higher ruthenium composition in the synthesized bimetallic nanoparticles. The control of the molar ratio of the precursors in the reactant solution was found to be employed as a means to control the composition of the elements in bimetallic nanoparticles.

摘要

采用氯化铁和氯化钌作为前驱体，通过液相等离子体（LPP）法合成了双金属铁-钌氧化物纳米颗粒。在LPP过程产生的等离子体场中观察到了活性物种（OH·、Hα、Hβ和O(I)）以及铁离子和钌离子。通过LPP反应合成了球形双金属铁-钌氧化物纳米颗粒，颗粒尺寸随着LPP反应的进行而增大。合成的双金属铁-钌氧化物纳米颗粒由Fe2O3、Fe3O4、RuO和RuO2组成。钌的还原电位高于铁，导致合成的双金属纳米颗粒中钌的组成更高。发现控制反应物溶液中前驱体的摩尔比可作为控制双金属纳米颗粒中元素组成的一种手段。
