Description

Packaging

100 mL in poly bottle

Application

This material is highly monodisperse in size and shape (<0.25 polydispersity index), and provides significantly improved surface reactivity. It is stable at high suspension densities when utilized at the recommended pH range. Applications include emissions catalysis, fuel cell electrolytes, polishing of optical surfaces, planarization of semiconductors, as a substrate for precious metals used in oxidation catalysis, catalysis for the splitting of water for hydrogen production, and as a radical oxygen scavenger in biological systems.
