| Abstract: | In this study, the catalyst of heteropolyacid with Keggin structure was successfully synthesized. The influences of the rare-earth element La, Ce, and Pr used as additive in the catalysts has been studied by means of XRD, IR and TG-DTA technology. The results showed that the addition of rare earth to Mo-P-O heterolpolyacid catalyst could improve its thermal stability and stabilizing the structure of H3PMo12O40. However, iso-butyric acid can be adsorbed on surface of Mo-P-O heterolpolyacid and it led to a strong adsorption after adding La, Ce and Pr. |
