Non‐oxidative Dehydrogenation of Methanol to Formaldehyde over Bulk β‐Ga ₂ O ₃

The non-oxidative dehydrogenation of methanol to formaldehyde is considered a dream reaction compared with the classical oxidative route, because valuable coupled product hydrogen formed instead water, and produced anhydrous highly suitable for further synthesis oxygenated synthetic fuels. This study reports on high catalytic performance pure β-Ga2O3 in this at temperatures between 500 °C 650 °C. At 550 GHSV 45500 h−1, an initial selectivity 77 % was obtained conversion 72 %. Performing beyond range lower resulted selectivity. catalyst suffered from deactivation caused by formation carbon deposits, but it possible regenerate its activity completely treatment. Irreversible occurred due partial volatilization Ga2O3.
