Structure-directed synthesis of Cr2O3/WO3·0.33H2O adsorbents for rapid removal of cationic pollutants.
Structural modulation is essential to advance adsorption performance. Herein, amorphous Cr2O3-modified crystalline WO3·0.33H2O composites were fabricated via a hydrothermal-heating route using chromium acetate as a structure-directing agent. Adjusting the Cr/W precursor molar ratio tailors the material microstructure,...
