The promotion effect of hydrogen spillover on CH4 reforming with CO2 over Rh/MCF catalysts

- Rh/MCF with different rhodium dispersion was studied in CH4 reforming with CO2.
- TOF(CH4) increased with the strength rise of spilt-over hydrogen on Rh/MCF.
- The promotion mechanisms were investigated by controlled atmosphere MAS NMR.
- Hydrogen spillover promotes the reforming by facilitating rate determining steps.
