asymmetric, interconnected, slit-like mesoporosity in the
samples [29]. It is to be noted that the uptake of nitrogen
increased steeply above the relative pressure of 0.7. The
corresponding BJH pore size distributions derived from
desorption data of the isotherms are shown in the insets of
Fig. 5. For TiO2 samples, the pore size distributions were
wider than those of Ag–TiO2 samples. It was due to partial
filled-in of the pores with the Ag nanoparticles in the samples.
The textural properties (BET surface area, total pore volume
and pore diameter) of TiO2 and Ag–TiO2 samples are shown in
Table 1. It indicates that BET surface area, total pore volume
and pore size of TiO2 samples were higher than those of Ag–
TiO2 samples. It demonstrated that the presence of Ag
nanoparticles within the pores lowered the textural properties
of the samples.
