(a) Pseudo first-order and pseudo second-order kinetic models for degradation of 10 ppm MB in presence of sample S4 as catalyst and ZrO2 balls with 350 RPM in speed at different temperatures: 20 °C (black curve), 40 °C (red curve), and 70 °C (blue curve). (b) LNK Vs 1/T Plot for the experimental data for the evaluation of thermodynamic Parameters of the degradation of MB. (c) Activation energy for decomposition of MB by piezo catalyst based on Arrhenius equation.
