| 摘 要： | 近来,用ESR方法研究吸附在催化剂载体表面上的氧氮自由基行为引起了广泛的兴趣,Lozos等[1]观察到DTBN在Al3O3-SiO3等载体上有两种谱:一种是14N(I=1)所引起的三重谱;另一种是27Al(I=5/2)引起的六重谱。

| Abstract: | The ESR spectra of TEMPONE radical on the activated Al2O3 were studied. It is found out that the ESR spectra of well-resolved nitrogen hyperfine splittings from TEMPONE adsorbed at two distinct types of sites can only be obtained when the Al2O3 must be treated previously with the steam at elevated temperature to increase the adsorbed hydroxyl group on the Al2O3 surface. The nitrogen hyperfine constant AN increases with the increasing of Lewis acid strength.Thus it may be used as a measure of the strength of the surface acid. |
