Abstract
The magnetism and thermal stability of layered TiO2–MoS2 (LTM) were investigated. Compared with layered TiO2 (LT), the magnetization of LTM is reduced greatly. As verified by photoluminescence and X-ray photoelectron spectra measurements, the reduction of magnetization is related to the decreasing of oxygen vacancy and Ti3+. The temperature dependence of magnetism is only slightly different between LT and LTM, indicating that layer MoS2 has very little contribution to magnetism. The thermal stability of LTM was studied by heating the sample in Ar atmosphere at different temperatures. The layered structure of LTM is destroyed by heating at 100 °C because the MoS2 layer is changed into MoS2 particles by heating at this temperature.
