Resistance to sulfur poisoning of the gold doped nickel/yttria-stabilized zirconia with interface oxygen vacancy

Compared with Ni/YSZ-Ov, the NiAu-d/YSZ-Ov can not only weaken the sulfur adsorption, but also restrain the diffusion of sulfur to the interface oxygen vacancy. Instead, the adsorbed S at the oxygen vacancy is more easily to diffuse out of the interface oxygen vacancy site.233
