Morphology Control of TiO(2) Nanorods Using KBr Salt for Enhancing the Photocatalytic Activity of TiO(2) and MoS(2)/TiO(2) Heterostructures

In this study, the effect of KBr salt on the growth of TiO(2) nanorods (NRs) was systematically studied. The addition of KBr with different concentrations provides a controllable growth of TiO(2) NRs using hydrothermal method. The results revealed that the presence of KBr molecules affects the growt...

description In this study, the effect of KBr salt on the growth of TiO(2) nanorods (NRs) was systematically studied. The addition of KBr with different concentrations provides a controllable growth of TiO(2) 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, TiO(2) NRs were used for the preparation of MoS(2)/TiO(2) heterostructures. To study the influence of the morphology on their activity, TiO(2) NRs samples with different KBr concentrations as well as the MoS(2)/TiO(2) heterostructures were evaluated towards the photocatalytic degradation of Rhodamine B dyes.
