Chemical transformation of solution-processed Ag nanocrystal thin films into electrically conductive and catalytically active Pt-based nanostructures
Journal of Industrial and Engineering Chemistry(2019)
摘要
•A solution-processed, conductive Pt-coated Ag nanocrystal thin films was made by ligand exchange and electroless deposition.•Various structures of Pt-Ag core/shell or alloys were designed through control of the platinum-deposition conditions.•Pt-Ag alloy structure exhibits high catalytic activity toward the hydrogen evolution reaction.
