Recent Advances on the MOFs-Based Materials for the Elimination or Utilization of Typical Gaseous Pollutants

Metal-organic frameworks (MOFs) have ordered pore and cage structure, and its central metal ions can provide a uniform active site. Modifying MOFs or preparing MOFs composites and derivatives could enhance the properties of MOFs-based materials, such as improving stability of the framework, regulating the electronic properties near the active site, promoting oxygen migration or the formation of more active oxygen species, improving the photo-generated carrier migration, and increasing the affinity between the active site and the pollutants. In view of these advantages, MOFs-based materials show excellent performance in the removal and utilization of typical gaseous pollutants. This article summarizes the application of MOFs-based materials in the removal and utilization of typical gaseous pollutants (e.g. sulfur oxides, nitrogen oxides, carbon oxides, volatile organic compounds, and methane). The prospects and challenges of MOFs-based materials in the future research and practical work of gaseous pollutant removal are also proposed, in order to stimulate the enthusiasm for the development of more efficient MOFs-based materials.
