Recent Advances in Catalytic Materials for Water Sustainability
Abstract
This comprehensive review summarizes the current knowledge of homogeneous, modified, and supported materials, and provides insights into water sustainability by increasing water availability through the use of catalytic materials. Metal cations, disinfectants, and hydroxyl radical-producing species are investigated in the homogeneous treatment of wastewater, such as organics, micro-pollutants, and heavy metals. Iron and manganese oxides are primarily demonstrated to accomplish many oxidation treatments of polluted water, albeit under limited conditions. Meanwhile, modified materials in wastewater treatment have become an active field despite the many limitations imposed in homogenous reactions. Carbon materials with periodic and aperiodic structures continue to evolve rapidly in water treatment, due to the ability to modify these materials under relatively simple treatments. Applying metal oxides onto polymers continues to increase, primarily in the arena of heavy metal removal because of the ability to use the functional groups and metal oxides in capturing heavy metal contaminants. This review reveals that advanced materials with supported high-valence metal oxides and high regenerability have a promising future toward water sustainability.
