Morphology Control of TiO Nanorods Using KBr Salt for Enhancing the Photocatalytic Activity of TiO and MoS/TiO Heterostructures.

In this study, the effect of KBr salt on the growth of TiO nanorods (NRs) was systematically studied. The addition of KBr with different concentrations provides a controllable growth of TiO NRs using hydrothermal method. The results revealed that the presence of KBr molecules affects the growth rate by suppressing the growth in the lateral direction and allowing for axial growth.
