| Abstract: | Al2O3
and SiO2 nanoparticles effect photodegradation of carboxylic acids,
and their photonic efficiencies are comparable to those of TiO2 P25
Degussa, TiO2 Hombikat, TiO2 anatase, TiO2
rutile, ZnO, SnO2, and ZrO2 nanosemiconductors. All the
nanoparticles show sustainable photoactivity and the degradation rates increase
linearly with oxalic acid-concentration and photon flux. The photonic
efficiencies of degradation are in the order: formic acid > oxalic acid >
acetic acid > citric acid. The mechanism of photodegradation is discussed. |
