A unique method to fabricate NixMg1 − xO (111) nano-platelet solid solution catalyst for CH4-CO2 dry reforming
A facile solvothermal route is established to generate NixMg1 − x(OH)(OCH3) platelet covered by (001) facets. Thermolytic decomposition of NixMg1 − x(OH)(OCH3) is topotactic and leads to the formation of NixMg1 − xO solid solution enclosed by reactive Tasker III type (111) facets. Both Mg and Ni are found to be distributed evenly in the solid solution. The reduced NixMg1 − xO platelet is a stable catalyst in CH4-CO2 dry reforming for a 100 h test.
