Abstract

A porous bimetallic palladium-platinum (Pd@Pt) nanoparticles (NPs) are prepared by using two different surfactants, poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (Pluronic® F-127) and polyethylene glycol hexadecyl ether (Brij® 58). Using the Pluronic® F-127 results in a more porous structure and a larger electrochemically active surface area, even though the sizes of the Pd@Pt NPs prepared using the two different surfactants are similar, approximately 100 nm. It is revealed that the Pluronic® F-127 surfactant can introduce more electrochemically active sites into the Pd@Pt NPs nanoparticles, results in enhanced bisphenol A detection with better sensitivity.
