Thermogravimetric and Thermo-Differential Analyses

We will present some examples. The calculation or conversion degrees of the transformations can be made analogously as described before. 

In the decomposition of precursors, one determines the mass loss of the samples due to the removal of water and precursors or due to phase transformation during heating under an oxidizing atmosphere (O2) at a rate of about 10°C/min up to 

In general, materials are prepared by the precipitation method. For example, zirconium hydroxide obtained by hydrolysis of zirconium acetate ([CH3COO]4 [Zr] ) with ammonium hydroxide (NH4OH). (NH4OH). Calcination of the hydroxides give rise to zirconium oxide (Zr02) [62]. 

The deactivation test was performed with reforming of ethanol (H20/EtOH) at different temperatures for long test life. There was high formation of coke after 

3 h life test [34]. Spent catalysts were collected and analyzed by ATG/DTA and SEM/EDS.
