Methane Activation and Transformation on Polyoxometalates
Figure 6
13C CP-MAS NMR spectra of the solids obtained after: (a) reaction of 13CH3OH on SiO2 at 200°C and evacuation at 60°C; (b) adsorption of 13CH3OH on bulk HSiW and evacuation at 60°C; (c) adsorption of 13CH3OH on HSiW/SiO2 and evacuation at 60°C; (d) same as (c) but evacuation at 120°C; (e) adsorption of 13CH3OH on HSiMo/SiO2 and evacuation at 60°C.
