This study developed novel MgAlSnO mixed oxide catalysts for sustainable bioaviation fuel production from furfural aqueous solutions. These catalysts show excellent resistance to water poisoning, enabling efficient conversion.
Area of Science:
- Catalysis
- Materials Science
- Sustainable Chemistry
Background:
- Direct synthesis of bioaviation fuel precursors from furfural (FF) aqueous solutions is a sustainable goal.
- Metal oxide catalysts often suffer from water poisoning in aqueous reactions.
Purpose of the Study:
- To develop highly water-poisoning-resistant catalysts for aqueous C-C coupling of biomass-derived molecules.
- To investigate the mechanism of water poisoning resistance in MgAlSnO mixed oxides.
Main Methods:
- Synthesis of MgAlSnO mixed oxides from MgAlSn-LDH.
- Catalytic testing of FF and methyl isobutyl ketone (MIBK) aqueous C-C coupling.
- In situ DRIFTS, contact angle measurements, poisoning experiments, and DFT calculations.
Main Results:
- MgAlSnO-CA catalyst achieved 96% FF conversion in high water content systems.
- The catalyst demonstrated broad applicability in aqueous-phase C-C couplings.
- Water dissociation on acidic sites was identified as key to water-poisoning resistance.
Conclusions:
- MgAlSnO-CA offers a novel strategy to mitigate water poisoning in metal oxide catalysts.
- This work provides guidance for direct resource utilization of FF aqueous solutions for sustainable fuel production.
