Fabrication of one dimensional hierarchical WO/BiOI heterojunctions with enhanced visible light activity for degradation of pollutants.

One-dimensional (1D) hierarchical WO/BiOI p-n (WB) heterojunctions with different mass percentages of WO were fabricated through a precipitation process. Various analytical techniques were employed to characterize the resulting WB composites, and their photocatalytic properties were measured by the degradation of rhodamine B (RhB) and methylene blue (MB) under irradiation of visible light. The WB heterojunctions showed largely enhanced photocatalytic performance as compared to the pure photocatalysts.

Fabrication of a novel BiOI/KTaO p-n heterostructure with enhanced photocatalytic performance under visible-light irradiation.

In this study, a series of BiOI/KTaO p-n heterojunctions were prepared a facile chemical bath strategy. The photocatalytic properties of the catalysts was tested by the degradation of Rhodamine B (RhB) and phenol under visible light irradiation. The BiOI/KTaO composites exhibited improved photocatalytic efficiency compared to the individual catalysts.
