Synthesis, Characterization and Applications of Sustainable Advanced Nanomaterials

“…The final product of photodegradation is carbon dioxide and water, although other carbon-containing compounds at lower oxidation levels may be formed [135]. Examples of photocatalysts used to remove contaminants are:  Nanoparticles: titanium(IV) oxide (removal of acetone [136], methyl blue, met ange [137]), SnO2 (removal of benzene [138]), ZnO (removal of methyl blue [1 moval of methyl orange [140][141][142]), ZnS (removal of rhodamine [143]), Ag 0 (re of methyl blue [144]);  Nanotubes: titanium(IV) oxide (removal of formaldehyde [145]), Ta2O5 (remo toluene [146]);  Nanocomposites: TiO2/CoxOy (phenol removal [147]);  Nanowires: CdS (methyl orange removal [148]). From among gas pollutants, nitrogen oxide and nitrogen dioxide are parti toxic, the latter poses a particular threat to human health.…”
