铂-金交替修饰的铂核纳米颗粒的制备与表征
Preparation and Characterization of Pt Nanoparticles Alternately Modified by Pt and Au Atoms
【摘要】 通过吸附在铂纳米颗粒表面的氢交替还原氯金酸和氯铂酸,得到了复合型纳米颗粒Pt@Au/Pt,用UV-Vis光谱、TEM和XRD对其进行了表征.
【Abstract】 Pt@Au/Pt composite nanoparticles were prepared by hydrogen adsorption and alternatively reduction of HAuCl_ 4 and H_ 2PtCl_ 6. UV-Vis spectra, transmission electronic microscopy and X-ray diffraction were used to characterize the composite nanoparticles.
