Abstract:
The effects of the Li-doping on the reducibility and morphological properties of a NWgO catalyst have been investigated by TPR, BET surface area, TEM, XPS, H2, and CO chemisorption measurements. The roles of both the doping method (pre- and postimpregnation) and lithium loading (0.67-2.50 wt %) have been assessed. Lithium addition before calcination (preimpregnation) yields sintering of NiO, affecting the overall “distribution” of the Ni precursor across the MgO matrix. The promoting effect of Li’ on the reducibility of the NWgO system has been discussed. At high reduction temperatures (Tr L 600 “C), Li causes a collapse in the catalyst structure, resulting also in a dramatic sintering of the metal phase.
