摘要

The authors in this study used the sol-gel process to prepare Bi-doped TiO₂ as a novel electrocatalyst. Results show that Bi can be doped successfully into TiO₂ from 1%to 90%. The electrical conductivity of a 1%Bi-doped TiO₂ particle-suspended solution is increased nearly twice that of pure TiO₂. The electro-catalyzing property of the synthesized Bi-doped TiO₂ catalyst was performed under acidic conditions toward a methyl blue dye solution. The observed removal percentage of methyl blue dye was from 5%to 75%. The optimized electro-catalyzing condition was observed at 5%Bi-doped TiO₂ with a working voltage of 5 V.
