Tuning oxygen vacancy density via facet engineering of TiO2 for selective photocatalytic hydrogenation of 5-hydroxymethylfurfural

Key Points

• Enhanced photocatalytic hydrogenation decreases 5-hydroxymethylfurfural concentration significantly.
• Key findings demonstrate a 35% increase in hydrogenation efficiency with optimal oxygen vacancy density.
• The study involves facet engineering of TiO2 to optimize its photocatalytic properties.
• Oxygen vacancy density adjustments in TiO2 may enable more efficient hydrogenation processes, yet further real-world testing is warranted.
