“Sea Anemone”-like CeFe Oxides for High-Efficient Phosphate Removal

The excessive release of phosphorus is a prime culprit for eutrophication and algal bloom in the aquatic environment, there always an urgent need to develop effective methods deal with pollution. Ce-based oxide type compelling adsorbent phosphate removal, self-templating strategy used construct high-performance oxides adsorption this study. A “sea anemone”-like CeFe cyanometallate (CM) 3D microstructure fabricated provide precursor synthesizing CeFe-based (CeFe-CM-T) by high-temperature pyrolysis. as-prepared CeFe-CM-T maintains anemone” morphology well has abundant micropores/mesopores, which render its superior capacity 1~2 orders magnitude higher than that commercial CeO2 Fe3O4 materials. Moreover, shows high selectivity removal when it co-exists other anions natural organic matter exhibits excellent recycling performance. It demonstrates both Ce3+ Ce4+ are reserved oxides, where serves as main active site capture, forms stable Ce-PO4 compounds via ligand-exchange mechanism. Thus, using CM potential method porous removal.
