Abstract

A study of the structure and catalytic performance of Li doped MgO catalysts is presented. The addition of Li to MgO causes a loss of the characteristic morphology of the precursor MgO due to agglomeration of crystallite grains. Growth of MgO grains leads to the formation of grain boundary dislocations. In addition, dislocations are also observed in the bulk of the grains. These dislocations are immobile and are suggested to be of the type a/2(110) and are probably pinned by Li+ segregating to the line of the defect. The importance of these dislocations is discussed with relevance to the partial oxidation of methane.
