摘要：

In this study, we reported a novel synthesis route of Bi2Ti2O7 pyrochlore by acetone solvothermal method. The bismuth nitrate and tetrabutyl titanate were used as reactant, and acetone was used as solvent. XRD patterns showed that the pure Bi2Ti2O7 particles were synthesized when the molar ratio of Bi/Ti was between 0.4 and 0.8. The SEM showed that the Bi2Ti2O7, crystal was uniform spherical particles. The carboxylic acid produced in the reaction system may be the main factor of bismuth mineralization. Compared with TiO2, pure Bi2Ti2O7 photocatalyst exhibited superior photo catalytic activity for methyl orange (MO) and tetracycline hydrochloride (TC) under simulated solar light. The possible formation mechanism was proposed.
