Fig. 2. Characterization and analysis of TiO2 NPs. (A) BJH pore size distribution and plot of the adsorption isotherm of TiO2 NPs. The BET surface area was 79.299 m2 g−1. The total pore volume for pores with a diameter of less than 343.88 nm at P/P0 = 0.9944002 was 0.5062 cm3 g−1. (B) The average pore diameter of TiO2 NPs was 25.54 nm.
