The several hydrotalcites investigated as precursors of catalysts by Angelo Vaccari

Hydrotalcite-derived catalysts are applied in a very broad range of processes. In this paper, the contribution of Angelo Vaccari's work to the development of these catalysts is reported. His work spanned from the preparation of novel hydrotalcites in powder and in structured forms, which after thermal treatments are applied in gas phase catalytic processes for reactions of hydrogenation, steam and dry reforming, partial oxidation, condensation and environmental applications. Moreover, he reviewed several aspects of hydrotalcite-derived catalysts. In this work, we summarize the main results that Angelo Vaccari together with his numerous co-workers has achieved.
