The experiments of TPD show that the adsorption of SO〓 on the surfaces of γ-Al〓O〓 and catalysts favors the formation of NO oxidative adsorption species which can desorb NO〓 at higher temperatures.

Pt/γ-Al〓O〓和NiO/γ-Al〓O〓上的DRIFT实验表明，NO-O〓在两种催化剂上形成的吸附物种有所不同。室温吸附NO-O〓时，前者表面上的硝酸盐物种较少，硝基或亚硝酸盐物种较多；后者则相反。
