A new wood veneer-based composite featuring Pt-loaded NiFe-LDH nanosheets is developed to effectively remove gaseous formaldehyde using a low-energy process.
The NiFe-LDH nanosheets capture formaldehyde through their hydroxyl groups, while Pt nanoparticles enhance the reaction to convert formaldehyde into CO and water.
Tested in a dark environment at room temperature, this composite successfully degrades nearly all formaldehyde within 30 minutes and retains over 97% efficiency after 10 cycles, making it a promising option for indoor air purification and decorative use.
