The catalysts containing 80 mol% Ce and 20 mol% Zr exhibited the most efficient performance, which could be attributed to a good balance between the basic and acidic sites on its surface. The DMC yield was successfully improved further from 0.24% to 1.6% by phosphate modification of Ce0.8Zr0.2O2. %L 540 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00002616 %U http://purl.uni-rostock.de/rosdok/id00002616 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002616-6 %U https://d-nb.info/1293658936/34 %U https://doi.org/10.18453/rosdok_id00002616
