Alumina supported cobalt nitride [Co 4 N-Al 2 O 3 (HT)] with high cobalt loading has been prepared for the first time from Co-Al hydrotalcite precursors. The formation of the Co 4 N phase was confirmed by XRD, H 2 -TPR, and XPS. Compared with Co 4 N/Al 2 O 3 (IMP) prepared by conventional impregnation and nitriding, the hydrotalcite derived catalyst exhibited a much better activity for hydrazine decomposition as consequence of higher dispersion of active species.

“…The mixed metal oxide catalysts derived from hydrotalcitetype compounds are reported to have good performances in N 2 O decomposition [4][5][6][7][8][9][10][11][12]. However, the conversion efficiency of the catalysts becomes seriously reduced when NO x , oxygen or water are present in the process.…”

“…Some catalysts, such as Cu-ZSM-5 and Rh-ZSM-5 reported by Li and Armor [4], and Rh supported on ZnO reported by Oi et al [5], were found to have prominent activities among the catalysts screened so far. Fe-exchanged zeolites are also noticeable for their selective catalytic reduction efficiencies with hydrocarbon reducing agents in the presence of oxygen [6,7].…”

“…Li and Armor [42] have carried out the ''sought for'' reaction over metal-exchanged zeolites and showed that Cu-ZSM-5 and Rh-ZSM-5 are the best catalysts among the catalysts screened. Oi et al [43,44] have claimed that Rh supported on ZnO is superior in activity over metal-exchanged zeolites. However, owing to the sensitivity of Cu-ZSM-5 to water vapor at high temperature and cost of precious metals, the catalysts are unattractive in commercial view point.…”

Hydrotalcite-like (HT-like) materials have been studied extensively in the last three decades. Although these materials initially perceived as potential anion exchangers, unrelenting efforts have also been attempted to use them as catalytic materials or as catalytic supports. There are varied ways by which one can use them for catalysis viz.; 1. Use them in as-synthesized form 2. Use them after calcining where the structural integrity of layered lattice is lost 3. Use the interlayer as functional spaces with moieties of catalytic interest 4. Use them after destruction or delamination and restructuring and 5. Use them as support or matrix. In this review, we are reporting the catalytic applications of HT-like materials and their derived forms carried out in our research group for the last 15 years in these various ways, covering reactions such as nitrous oxide decomposition, selective oxidation of organic compounds of industrial relevance and base-catalyzed isomerization of chemicals of perfumery interest. Although this review primarily focuses on our work, wherever applicable, related or relevant works from other groups are also presented to bestow comprehensiveness.
