摘要
以硝酸铋、钼酸铵和CTAB为原料,在氢氧化钠存在下160°C水热反应12h,成功制备了BiOBr/Bi_2MoO_6微纳结构。研究显示,合成的花状的BiOBr/Bi_2MoO_6微纳结构在可见光下具有比单一的Bi OBr和Bi2Mo O6更好的催化降解罗丹明B和有机污染物的能力。其高效的光催化活性可归功于花状的结构及Bi OBr-Bi2Mo O6异质结的形成。所得的BiOBr/Bi_2MoO_6纳米复合材料可作为一种良好的可见光催化剂,在环境治理与防护领域有潜在的应用。
BiOBr/Bi_2MoO_6 nanocomposites were synthesized by a simple hydrothermal reaction, employing bismuth nitrate, ammonium molybdate, and CTAB as the raw materials in the presence of proper amounts of Na OH. Research showed that the flowerlike BiOBr/Bi_2MoO_6 nanostructures exhibited higher photocatalytic activity in degrading Rh B and other organic pollutants than single BiOBr or Bi_2MoO_6 under visible-light irradiation. The enhanced photocatalytic activity was mainly attributed to the flowerlike structure and the formation of BiOBr/Bi_2MoO_6 heterojunction. The present BiOBr/Bi_2MoO_6 nanocomposites can be used as an effective visible-light-driven photocatalyst and have potential applications in the field of environmental treatment and protection.
