Abstract
Pd-CeO2 nanocrystals were prepared using a simple surfactant induced method, which initiated dry reforming of methane reaction only at 350°C. Low temperature activity of the prepared catalyst was due to high Pd-dispersion and very good redox property of support Ceria (20–50nm) nanocrystals (32.8% Ce+3 concentrations). The catalyst was found to be very good coke resisting and inhibited deactivation by coke formation during catalysis. Time on stream (TOS) study was carried out for 12h and slight decrease in conversion was observed due to sintering, re-oxidation and hydroxylation of the active Pd-nanoparticles.
