| Abstract |
We investigated the effect of CeO2 content on the catalytic behavior of (68-x)P2O5-32ZnO-xCeO2 (x = 0, 4, 8, 12, and 16 mol%) glasses. In addition, we confirmed the effect of the addition of B2O3 on the catalytic properties of (60-x)P2O5-32ZnO-8CeO2-xB2O3 (x = 0, 5, 10, 15 and 20 mol%) glasses. Using TGA, we confirmed that the catalytic activity of the (68-x)P2O5-32ZnO-xCeO2 glasses increased with CeO2 content. Furthermore, the catalytic activity of (60-x)P2O5-32ZnO-8CeO2-xB2O3 decreased until the B2O3 content attained 15 mol%, beyond which, it increased. The change in the catalytic properties in relation to the content of B2O3 and CeO2 was analyzed through FT-IR, XPS, optical band gap energy, and density. |
