Abstract

Rare earth oxides, which generally take the form Ln2O3, are widely used in heterogeneous catalysis. This article provides a brief description of the Ln2O3 oxides, which includes a comparison of their chemical and physical properties. The basicity of heterogeneous oxides is examined, and the different pKa's on the surface are modeled. The catalytic properties of the oxides will be correlated with their various chemical and physical properties. Several different examples of their use in rare earth heterogeneous catalysis will be described including oxidative methane coupling and transesterification of triglycerides.
