Contrasting dynamic responses of supported Rh nanoparticles to H2S and SO2 and subsequent poisoning of NO reduction by H-2

Contrasting dynamic responses of supported Rh nanoparticles to H2S and SO2 and subsequent poisoning of NO reduction by H-2
Contrasting dynamic responses of supported Rh nanoparticles to H2S and SO2 and subsequent poisoning of NO reduction by H-2
H2S induces rapid sulfidation of the Rh nanoparticles at room temperature and completely poisons NO reduction by H-2; SO2 elicits an equally rapid but subtle modification of nanoparticle structure but has little effect upon NO reduction at 523 K.

Abstract

H2S induces rapid sulfidation of the Rh nanoparticles at room temperature and completely poisons NO reduction by H-2; SO2 elicits an equally rapid but subtle modification of nanoparticle structure but has little effect upon NO reduction at 523 K.
