Carbon dioxide reforming of methane over promoted NixMg1−xO (1 1 1) platelet catalyst derived from solvothermal synthesis

- A facile solvothermal and topotactic transformation route to generate M-NixMg1−xO (1 1 1) platelet (M = Sn, Ce, Mn or Co) catalyst is established.
- Mn- and Ce-segregate as separate phase and do not enhance the coke-resistant performance of NixMg1−xO (1 1 1) platelet catalyst.
- Co- and Sn-promoted NixMg1−xO (1 1 1) platelet catalysts inhibit Cβ formation in CH4-CO2 dry reforming reaction, as they are uniformly distributed on the catalyst.
- Co does not passivate Ni activity and displays superior coke-resistance properties under harsh reaction conditions.
