Microemulsion flame pyrolysis for hopcalite nanoparticle synthesis: A new concept for catalyst preparation

Abstract

A new route to highly active hopcalite catalysts via flame spray pyrolysis of an inverse microemulsion precursor is reported. The nitrate derived nanoparticles are around 15 nm in diameter and show excellent conversion of CO under ambient conditions, outperforming commercial reference hopcalite materials produced by co-precipitation.
