Rapid fluorescent mapping of electrochemically induced local pH changes

Rapid fluorescent mapping of electrochemically induced local pH changes

We present a fluorescent microscopic method using an ultra-pH-sensitive polymeric probe to rapidly map within subsecond the pH distribution resulting from oxygen reduction reaction electrocatalysed by an array of platinum nanoparticles. Upon voltammetry of the surface-supported Pt catalysts, fluores...
