N2 adsorption-desorption isotherms of BC/TiO2 and SMBC/TiO2 nanocomposites are shown in Fig.3.The curves show a classical type-IV characteristic，suggesting the presence of mesopores.Then the textural properties of nanocomposites were analyzed by Brunauer-EmmettTeller（BET）and Barrett-Joyner-Halenda（BJH）methods.Table 1 shows the specific surface area（SBET），pore size，and pore volume（Vt）of BC/TiO2 and SMBC/TiO2 composites.Due to the aggregation of TiO2 nanoparticles and poor water-dispersibilities of BC，SBET of BC/TiO2nanocomposites was only 71 m2/g.By using SMBC as supporting materials，TiO2 nanoparticles can be loaded uniformly on the surface and SMBC/TiO2 nanocomposites display much higher SBET and pore volume.SBET is155 m2/g，nearly 2.2 times as large as BC/TiO2.The higher SBET and Vt would offer more surface active sites and do favor to improve the adsorption and photocatalytic degradation performance.
