TiO2-loaded mesoporous adsorbent has been prepared by hydrothermal method using P123 as the template and Tetraethyl orthosilicate(TEOS) as the silica source.The composition was characterized by FT-IR and XRD.The results based on the analysis of the nitrogen isotherms and TEM showed that the pore diameter of sample PS1 and PS2 was 5.23 nm and 4.90 nm
the specific surface area was 798.97 m2/g and 866.64 m2/g
respectively.The photocatalysis results of the mesoporous adsorbent indicated that the maxmum adsorption capacity of PS1 to Rhodamine B(RB) and Methylene Blue(MB) was 23.79 mg/g and 17.56 mg/g
PS2 to RB and MB was 23.05 mg/g and 20.05 mg/g
respectively;The maxmum catalytic capacity of PS1 and PS2 to RB can all reach to 25.2 mg/g or so in 50 min and 120 min respectively
to MB can all reach to 24.9 mg/g in 25 min
respectively.Those results showed that PS1 and PS2 had better catalytic effect than RB.
