我们采用穆斯堡尔谱学方法研究了配比、焙烧温度和载体含量不相同的Fe_2O_3-Sb_2O_4催化剂。这些催化莉的穆斯堡尔谱中,都有同质异能移为0.67mm/s和四极分裂为0.78mm/s的Fe~(3+)处于FeSbO_4中的双峰。在焙烧温度高于600℃的富锑催化剂中,除有Fe~(3+)的特征峰外,还出现了同质异能移为1.32mm/s,四极分裂为3.32mm/s的Fe~(2+)处于FeSb_2O_6中的双峰。 We use the Mossbauer spectroscopy method to study the proportion, calcination temperature and carrier content of different Fe_2O_3-Sb_2O_4 catalyst. These catalytic Miebauer spectra all have bimodal Fe 3+ in FeSbO 4 with a homoplasia of 0.67 mm / s and a tetrapod of 0.78 mm / s. In addition to the characteristic peaks of Fe ~ (3+), the antimony-rich catalysts with a calcination temperature higher than 600 ℃ also showed the same energy shift of 1.32mm / s and the tetrad splitting of 3.32mm / s Fe ~ (2+) bimodal in FeSb_2O_6.
