Metal organic framework-assisted sonodynamic oxidation platform for removing organic contaminants in water

With the fast-track progresses in adsorptive/catalytic technology and micro/nano-materials, the water remediation including the pollutant removal has benefited greatly. This review starts with the main physical and chemical treatments of organic contaminants, and provides a brief comprehension for advanced oxidation process. Then by putting some details on the ultrasonic cavitation, it discusses the probable principles of sonodynamic oxidation (SDO) in a fundamental understanding, and describes the assistance of oxidant precursors, heterogeneous catalysts and energy inputs in the SDO. As well, the perception of metal organic framework (MOF) in the water remediation is provided according to the behaviors, highlighting the unique advantages of MOF as adsorbents or catalysts. More importantly, the review hierarchically overviews the recent advances of MOF-assisted SDO platform, and via the deep observations toward the methodologies, performances and mechanisms, it emphasizes on the extension services or opportunities of MOF-assisted SDO platform to remove organic contaminants. Last but not least, some challenges and prospects are proposed to enrich the performance improvements and theoretical innovations for the MOF-assisted SDO platform in the water remediation applications.
