Pt nanoparticles: Heat treatment-based preparation and Ru(bpy)(3)2+-mediated formation of aggregates that can form stable films on bare solid electrode surfaces for solid-state electrochemiluminescence detection.

Journal Article (Journal Article)

A simple thermal process for the preparation of small Pt nanoparticles is presented, carried out by heating a H2PtCl6/3-thiophenemalonic acid aqueous solution. The following treatment of such colloidal Pt solution with Ru(bpy)(3)2+ causes the assembly of Pt nanoparticles into aggregates. Most importantly, directly placing such aggregates on bare solid electrode surfaces can produce very stable films exhibiting excellent electrochemiluminescence behaviors.
