Synthesis and characterization of NiO-YSZ for SOFCs

Nickel oxide and yttria-stabilized zirconia ceramic materials were prepared by three methods: physical mixture, a modified Pechini route, and impregnation with Ni(NO 3) 2·6H 2O. Temperature-programmed reduction (TPR) analysis showed the presence of different reduction peaks for each sample and that...
