Pd-CeO2 nanocrystals were prepared using a simple surfactant induced method, which initiated dry reforming of methane reaction only at 350 degrees C. Low temperature activity of the prepared catalyst was due to high Pd-dispersion and very good redox property of support Ceria (20-50 nm) 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 12 h and slight decrease in conversion was observed due to sintering, re-oxidation and hydfoxylation of the active Pd-nanoparticles.
