The 3D open Bi(2)MoO(6)/ZnTiO(3) hierarchical heterostructures with Bi(2)MoO(6) ultrathin nanosheets (<10nm) grown on hexagonal-phase ZnTiO(3) nanofibers were fabricated by combining the electrospinning technique and solvothermal method. And, the Bi(2)MoO(6)/ZnTiO(3) hierarchical heterostructures had remarkable light absorption in the visible region. The photocatalytic studies revealed that the hierarchical heterostructures system exhibited exceptional photocatalytic activity in visible-light degradation of Rhodamine B, which might be attributed to the synergistic system with excellent charge separation characteristics and the unique morphology of Bi(2)MoO(6) nanosheets with the extended absorption in the visible light region. What is more, the 3D open structure supported on nanofibrous candidates possessed large surface areas and excellent recyclability.
采用静电纺丝技术和溶剂热法制备了具有 3D 开放结构的 Bi(2)MoO(6)/ZnTiO(3)分级异质结构，其中 Bi(2)MoO(6)的超薄纳米片(<10nm)生长在六方相 ZnTiO(3)纳米纤维上。并且，Bi(2)MoO(6)/ZnTiO(3)分级异质结构在可见光区域具有显著的光吸收。光催化研究表明，分层异质结构体系在罗丹明 B 的可见光降解中表现出优异的光催化活性，这可能归因于具有优异电荷分离特性的协同体系和 Bi(2)MoO(6)纳米片的独特形态，使其在可见光区域具有扩展的吸收。更重要的是，负载在纳米纤维候选物上的 3D 开放结构具有较大的比表面积和优异的可回收性。
