Graphene oxide enhanced amine-functionalized titanium metal organic framework for visible-light-driven photocatalytic oxidation of gaseous pollutants

Graphene oxide (GO) enhanced amine-functionalized titanium metal organic framework (NH2-MIL-125(Ti)) was fabricated via a facile microwave solvothermal process. Benefiting from the strong interaction and high electronic conductivity of GO, the as-obtained hybrid system was proved highly efficient for photocatalytic oxidation of gaseous pollutants (NOx) and acetaldehyde with long durability, under visible light (λ > 420 nm) irradiation.
