使用氢还原和辐解技术制备Pt-Au和Au-Pt核壳型的双金属金和铂颗粒。记录光吸收光谱并与文献中描述的各种Au−Pt颗粒进行比较。AuCorePtshell颗粒催化银离子的氢还原以产生三金属颗粒。
Bimetallic gold and platinum particles of the Pt−Au and Au−Pt core−shell type are prepared using hydrogen reduction and radiolysis techniques. The optical absorption spectra are recorded and compared to various Au−Pt particles described in the literature. AucorePtshell particles catalyze the hydrogen reduction of silver ions to yield trimetallic particles.
