A zero-carbon emission chemical method to remove gaseous formaldehyde at room temperature by a renewable aminooxy-functionalized graphene composite.

We prepared a composite of aminooxy bifunctional molecules with graphene, which can decompose 91 mg of HCHO by 1 g of bifunctional molecules at room temperature with the only byproduct of water. Moreover, the composite can be regenerated under acidic conditions and 83.5% capacity is retained after 10 cycles.
