Metal-Organic Frameworks for Air Pollution Purification and Detection

Metal-organic frameworks (MOFs), an emerging class of porous crystalline material, are identified as a promising candidate for tackling the most formidable global challenges due to their unique and intriguing properties including well-defined porous crystal structure, large specific surface area, and vast tunable chemical and physical property. Air pollution resulting from various toxic gases, volatile organic compounds, and fine particulate matters has posed a big threat to human health and ecological sustainability. In recent years, various MOFs are studied and shown great potential as active materials for air pollution control in both pollutant detection and air quality remediation. In this review, the most recent research progress for MOFs-based materials for air pollution control is summarized. The discussion is categorized based on the different approaches for air quality control with a focus on the performance correlations to the structure and functionality of MOFs. In addition, the technical merits and downsides of each approach are discussed based on their application scenarios. Finally, the remaining challenges and future research directions in this field are proposed.
