25. 3 cubic space of was carried out using the following assumptions. Initially, the time necessary to remove the reactant by means of a photocatalytic reaction on one of the walls was calculated on the basis of a one-dimensional mass transport model, using eqs 2 and 4 with z = 3 m. This time was then divided by a factor of 6 due to the presence of six walls. The concentration decrease in the boundary layer was assumed to be compensated by the supply of the compound from the bulk of the gas phase, and the dilution ratio in the bulk phase was assumed to be proportional to the distance from the substrate. However, the circulation time outside the boundary layer for dilution was not considered.
