In Operando Nuclear Magnetic Resonance Spectroscopy Study on Photocatalytic Methanol Reforming

doi:10.11938/cjmr20182680

Abstract

Abstract: 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.

Key words: in operando NMR, methanol reforming, photocatalytic, liquid-state NMR
