Morphology Control of TiO₂ Nanorods Using KBr Salt for Enhancing the Photocatalytic Activity of TiO₂ and MoS₂/TiO₂ Heterostructures.

ABSTRACT: In this study, the effect of KBr salt on the growth of TiO₂ nanorods (NRs) was systematically studied. The addition of KBr with different concentrations provides a controllable growth of TiO₂ 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. This results in affecting the morphology by decreasing the diameter of the nanorods, and increasing the free space between them. Enhancing the free spaces between the adjacent nanorods gives rise to remarkable increase in the internal surface area, with more exposure side surface. To obtain benefit from the enlargement in the inner surface area, TiO₂ NRs were used for the prepara
