Ultraselective low temperature steam reforming of methanol over PdZn/ZnO catalysts Influence of induced support defects on catalytic performance

The influence of the calcination atmosphere of ZnO precursor (Zn-4(CO)(3)(OH)(6)center dot H2O) on the catalytic performance of a series of PdZn/ZnO catalysts was studied for production of H-2 via low temperature (180 C) direct methanol steam reforming (low temperature-MSR). The catalytic activity and selectivity of PdZn/ZnO were found to be strongly influenced by the calcination atmosphere of ZnO precursor and increased from oxidizing to reducing atmosphere, following the order (O-2 < air < N-2
