【摘要】 本文测定并讨论了Cu²⁺在X,Y,A型分子筛和SiO₂,γ-Al₂O₃,SiO₂-Al₂O₃等六种载体上的ESR波谱,以及在这些Cu²⁺-载体上吸附吡啶、吡咯、苯胺等含氮化合物的ESR波谱。利用测得的波谱参数,计算了载体表面的晶体场能,以及被吸附分子在这些载体表面上生成配位络合物的化学键参数和配位场能。更多还原

【Abstract】 The ESR spectra of Cu(Ⅱ)on zeolite of type X, Y, and A, and on silica,γ-alumina and silica-alumina both in the absence and in the presence of adsorbed pyridine, pyrrole and aniline were measured and discussed. The crystal field energies in the environment of the bare supporters, and the bonding parameters and ligand field energies due to the coordination of the adsorbed nitrogen compounds were calculated.更多还原
