Estimate of the basicity of Ln[sub 2]O[sub 3]-Bi[sub 2]O[sub 3] catalysts for oxidative couping of methane through diffuse reflectance UV-vis experiments

The present work is aimed toward estimating the basicity rare earth oxide/bismuth oxide catalysts based in the electronic structure of the solid. The stabilization of the [beta]-Bi[sub 2]O[sub 3] phase due to the presence of rare earth cations allows the separation of the role of the basicity of the...

Description
Summary:The present work is aimed toward estimating the basicity rare earth oxide/bismuth oxide catalysts based in the electronic structure of the solid. The stabilization of the [beta]-Bi[sub 2]O[sub 3] phase due to the presence of rare earth cations allows the separation of the role of the basicity of the catalysts from the influence of the crystalline structure in the activity in the oxidative coupling of methane. 13 refs., 3 figs., 2 tabs.
