摘要：
Using organic aqua regia,a recently discovered powerful organic leaching agent,an effective process of recovering Pt directly from Pt-Au bimetallic nanoparticles was demonstrated.The purities of the Pt recovered from a mixture of Au and Pt nanoparticles and from Pt-Au core-shell nanoparticle catalyst are as high as (99.49±0.22)%,and (95.02±0.08)%,respectively.The novel recovery process promises applications in catalysis industry.
