Assessing the Effect of Dopants on the C-H Activation Activity of γ-Al O using First-Principles Calculations.

In recent years, the high availability of methane in the shale gas reserves has raised significant interest in its conversion to high-value chemicals but this process is still not commercially viable. Metal oxides, due to their surface heterogeneity and the presence of Lewis acidic and basic site pairs are known to facilitate the activation of C-H bonds of methane. In this work, we investigate the C-H bond activation of methane on pristine and doped γ-Al O clusters using density functional theory (DFT) calculations.
