Keywords: | Nonisothermal kinetics;Reduction by hydrogen;Silver(I) oxide;Thermogravimetry | Issue Date: | 10-Nov-2011 | Journal: | Thermochimica Acta | Abstract: | The reduction of silver(I) oxide to metallic silver by gaseous hydrogen was studied by means of thermogravimetric analysis, at constant heating rates in the range 2.5-30 °C min-1. Under these conditions the reduction process completed in the temperature range 60-190 °C. Both the expanded Friedman's isoconversional method and Kissinger's method were used to determine the activation energy, and very similar values, 59.6 kJ mol-1 and 59.7 kJ mol-1, respectively, were obtained. The expanded Friedman's isoconversional method, involving the first order reaction model, enabled the satisfactory fit of the experimental data. © 2011 Elsevier B.V. All rights reserved. |
