Bi₂MoO₆ nanoflakes are synthesized via a normal hydrothermal method. Bi₂MoO₆ photocatalysts show lower photocatalytic activity for the degradation of methylene blue under visible light irradiation. In order to further enhance the degradation efficiency, Bi₂MoO₆ is used to activate the peroxymonosulfate for the degradation of methylene blue under visible light. Bi₂MoO₆ nanoflakes show excellent degradation efficiency in the Bi₂MoO₆/Vis/peroxymonosulfate (PMS) system. Moreover, the influences of PMS dosage, pH value, and inorganic anions on photodegradation are evaluated. The mechanism of activating peroxymonosulfate is proved by radical quenching experiment, which reveals that sulfate radicals govern the removal of methylene blue.

Bi2MoO6 的合成和活化过硫酸盐以增强可见光照射下的光催化活性

Bi ₂ MoO ₆纳米薄片通过常规水热法合成。Bi ₂ MoO ₆光催化剂在可见光照射下对亚甲基蓝的降解表现出较低的光催化活性。为了进一步提高降解效率，采用Bi ₂ MoO ₆活化过硫酸盐，在可见光下降解亚甲蓝。Bi ₂ MoO ₆纳米薄片在Bi ₂ MoO _{6 中}表现出优异的降解效率/Vis/过氧单硫酸盐 (PMS) 系统。此外，还评估了 PMS 用量、pH 值和无机阴离子对光降解的影响。自由基猝灭实验证明了活化过一硫酸盐的机理，揭示了硫酸盐自由基控制着亚甲基蓝的去除。
