Shape-controlled synthesis of self-supported metallic nanocrystals with abundant active surface areas is ofvital importance for the design and fabrication of novel outstandingly excellent electrocatalysts. Motivatedby this, we herein report our research in the synthesis of self-supported porous 2D AuCu triangularnanoprisms via a facile wet-chemical method. Owing to the attractive 2D triangular structure,bifunctional and electronic effects between Au and Cu, such unique Au1Cu1 nanoprisms exhibitedextremely high catalytic activities towards ethylene glycol and glycerol electrooxidation with massactivities of 2873 and 2263 mA mgAu1, which are 3.0 and 3.9-fold enhancements over those of pure Au
(958 and 573 mA mgAu1), respectively. We trust this strategy may be extended to the syntheses of othermultimetallicnanocatalysts with such fascinating nanostructures and the as-obtained porous triangularnanoprisms can be well applied to serve as highly desirable anode catalysts for electrooxidation ofethylene glycol and glycerol.
