Oxidation Thermogravimetric Properties and Kinetic Analysis of Titanium Dioxide/Carbon Nanotubes (TiO_2/CNTs) Composites

Oxidation thermogravimetric properties were analyzed on titanium dioxide/carbon nanotubes(TiO2/CNTs) composites prepared through the hydrothermal method.The effects of heating rates and TiO2coated quantity were investigated.It was revealed that higher heating rate made thermogravimetric(TG) and differential scanning calorimetric(DSC) curves move to the area with higher temperature,while the higher TiO2coated quantity was on the contrary.However,the maximum weight losses were almost not affected by heating rates and TiO2 coated quantity.Thermogravimetric dynamic parameters(Ea,lnA) of TiO2/CNTs were obtained through the Kissinger and Ozawa method.The regression coefficient R2were over 0.99 which indicated good fitting results.
