摘要
Ruthenium, one of the platinum group metals, has drawn much attention due to its catalytic behavior, hardness, electrical conductivity and density. Ruthenium particles are usually prepared on a small scale by the polyol process, however, the size of the obtained ruthenium nanoparticles is most below 10 nm. In this work, ruthenium particles about 200 nm in diameter were obtained in aqueous solution by using ammonium formate as the reducing agent. To have a better control of particle's size and shape, the effects of PVP, mixing mode, reaction temperature, solution pH and calcination temperature were investigated.
