In situ crystallization of ZnAl2O4/ZnO nanocomposite on alumina granule for photocatalytic purification of wastewater
ZnAl 2 O 4 /ZnO nanocomposites with different ZnO (20, 30, and 40 mol%) concentrations and coated samples on supports were successfully prepared through combustion synthesis assisted by microwave. Two catalyst supports (α-Al 2 O 3 granules and γ-Al 2 O 3 granules) in the forming of granules were use...
