The catalytic thermo-oxidative decomposition of glimepiride using the isoconversional method

Abstract Applying the isoconversional method to data obtained from thermogravimetric analysis (TGA) can provide vital kinetic information. In this work, thermal decomposition and oxidation of antidiabetic drug glimepiride is analyzed in presence N 2 O . The study was done with without metal oxide catalysts explore their potential application solid wastewater upgrading. conducted using analysis. methods Kissinger–Akahira–Sunose Friedman were used estimate effective activation energies as a function extent conversion ( α ). Density functional calculations bond dissociation glimepiride. E values DFT indicate an initial S–N breaking pre-exponential factor A ) triplet (Δ H ‡ , Δ S G are also discussed. When studied oxides, catalyst activity found follow order $${\text{VO}}_{{2}} > {\text{ CuO }} MnO}}_{{2}} Al}}_{{2}} {\text{O}}_{{3}} TiO}}_{{2}}$$ VO 2 > CuO MnO Al O 3 TiO
