~(119m)Sn穆斯堡尔诺学从六十年代末期以来有了很大发展,它已深入到各个学科领域,在化学方面的应用尤为突出。1976年,我们首次利用~(119m)Sn穆斯堡尔谱研究新型高级脱氢Pt-Sn体系催化剂和性能优良的稀土钻永磁合金。本文扼要介绍了~(119m)Sn穆氏谱基本原理,重点讨论了应用于上述两个领域的研究成果和前景。 在新型铂-锡脱氢催化剂研究中,~(119m)Sn穆斯堡尔谱的研究不仅表明,铂存在促进了锡还原,(SnO_2)氧化+Pt→PtOx+(sn)还原,而且在一定程度上证明非络合浸渍法催化剂中铂与锡的相互作用不及络合法中的强,
~ (119m) Sn The Münster-Ernst Institute has greatly developed since the late 1960s. It has penetrated into various disciplines and has been particularly prominent in chemistry. In 1976, for the first time, we used ~ (119m) Sn Mössbauer spectroscopy to study novel advanced dehydrogenation Pt-Sn system catalysts and rare earth-based permanent magnet alloys with excellent properties. This paper briefly introduced the basic principle of ~ (119m) Sn Muhs spectrum, and focused on the research results and prospects applied to the above two fields. In the study of the new platinum-tin dehydrogenation catalyst, the study of ~ (119m) Sn Mossbauer spectroscopy not only shows that the presence of platinum promotes the reduction of tin, the oxidation of (SnO_2) + Pt → PtOx + (sn), and to a certain extent On the non-complex impregnation method to prove the interaction of platinum and tin less than complex method in the strong,
