Novel continuous flow synthesis of Pt NPs with narrow size distribution for Pt@carbon catalysts

In this work, we report a novel continuous flow synthesis method to achieve ultra-small Pt NPs (2.3 to 2.5 nm) with narrow size distribution. This method expedited the synthesis of Pt NPs without any harsh reducing agent or capping agent. Further these Pt NPs were immobilized on a carbon support in...

Sumario:In this work, we report a novel continuous flow synthesis method to achieve ultra-small Pt NPs (2.3 to 2.5 nm) with narrow size distribution. This method expedited the synthesis of Pt NPs without any harsh reducing agent or capping agent. Further these Pt NPs were immobilized on a carbon support in a single step procedure for its application as an electrocatalyst for fuel cells. The synthesized Pt NPs and Pt NPs supported on carbon were analyzed using transmission electron microscopy affirming uniform distribution of Pt NPs throughout the carbon support without aggregation.
