Abstract
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.
