用H2S(硫化氢)硫化TiO2的热重与质谱分析

The sulfurization of Titanium Dioxide (TiO2)by pure Hydrogen Sulfide (H2S) was successfully monitored using a simultaneous Thermogravimetry (TG) and Mass Spectrometer (MS) system. While confirming the progress of the reaction from TG and MS data, experimental results also showed that such a reaction was diffusion controlled. 采用热重与质谱同步分析，成功地监测了TiO2与纯的H2S硫化反应的全过程，并揭示了其扩散控制的机理
