Abstract B–doped TiO2 was prepared via sol–gel method, and was characterized using powder X–ray diffraction (XRD), scanning electron microscope (SEM), X–ray photoelectron spectrum (XPS), FT–IR, and N2 adsorption (BET). The results show that B doping inhibited growth of TiO2 crystal, and no apparent impact on surface morphology of TiO2 particles was observed. The doped boron mainly occupy the internal space of TiO2 crystalline structure, existing in the form of B–O–Ti structure. The samples doped with 3% (mass fraction) boron have the optimal performance of photocatalytic degradation of methyl orange. N2 adsorption isotherm showed that the BET surface area and average pore size of 3% B–TiO2 are 127.84 m2/g and 10.53 nm, respectively.
