In Operando Nuclear Magnetic Resonance Spectroscopy Study on Photocatalytic Methanol Reforming
Abstrak
The reaction of photocatalytic methanol reforming in a real solid-liquid reaction environment was studied by in operando nuclear magnetic resonance (NMR) spectroscopy. Four liquid-state intermediate products were detected in the reaction systems investigated, including HOCH2OH, CH3OCH2OH, HCOOH and HCOOCH3. It was also demonstrated that the crystal types of TiO2 catalysts had a strong influence on the production of the four intermediate products. And the contents of the four products increased with the increasing illumination time. Palladium (Pd) loading enhanced the production of CH3OCH2OH and HOCH2OH by 2~3 orders of magnitude, but had little effects on the production of HCOOCH3 and HCOOH.
