Abstract:
We investigated the effect of controlled periodic illumination on quantum efficiency of acetone vapor
photocatalytic oxidation. It was demonstrated that quantum efficiency increases with the increase of
light pulses frequency and decrease of the duty cycle and at some point reaches its maximum value
which is equal to the quantum efficiency obtained under the same average photon flux. Several kinetic
models were applied to the experimental data. The general conclusion was made that there are only two
kinetically distinguishable active species on TiO2 surface with the lifetimes in 10−3–101 s range.
