Mesoporous nano-titania photocatalysts were prepared by sol-gel method in acidic or basic media with or without three types of surfactants, namely, cetyltrimethyl ammonium bromide (CTAB), sodium dodecyl benzene sulfonate (DBS), and nonylphenol ethoxylate (NPE).The data obtained showed that at the low pH (acidic) range, the CTAB templated catalyst gave the highest surface area (86.7 cm3/g), which is mainly assigned to acquiring the highest phot...
