Abstract

A rotary-bed OMCVD device was developed and successfully applied to the scale-up of the preparation of supported rhodium nanoparticles. The device revealed suitability for the preparation of up to ten grams of material. A multistep CVD protocol was established and allowed a catalytic material with tailored structural/morphological properties of the supported nanoparticles to be obtained. As the result of this kind of catalyst design the supported Rh nanoparticles showed outstanding performance in the hydrogen production by methane catalytic partial oxidation at low contact times. Materials produced were fully characterized by a pool of techniques including HRTEM, CO-DRIFTS, TPRD, etc.
