- aExperimental values identified according to pore size distributions are given in brackets.
- Differential distributions of pore volume are given in Figure 7. The r values are represented as logr; the peaks are symmetric. Thus, the plots can be resolved by Lorentz functions. Since , the peak area gives the pore volume caused by each type of particles.
