Effect of Mn/Al ratio in Co–Mn–Al mixed oxide catalysts prepared from hydrotalcite-like precursors on catalytic decomposition of N2O

An influence of thermal treatment conditions of hydrotalcite-like materials on their catalytic activity in the process of N2O decomposition

“…The best results were obtained for the Co-Al sample with the Co/Al ratio of 3. Calcined Co-Mn-Al hydrotalcites were studied by Obalova et al [18][19][20], who proposed the optimal method for synthesis of effective catalysts and reported high activity of these oxide systems in the presence of O 2 and NO x . Chang et al [21] reported high activity of calcined Co-Al hydrotalcites containing additionally rhodium, palladium, or cerium in the process of N 2 O decomposition and reduction by carbon monoxide.…”

Mn-containing catalytic materials for the total combustion of toluene: The role of Mn localisation in the structure of LDH precursor

“…The use of layered double hydroxide (LDH)-type precursors has been recognised as a very promising method of obtaining mixed oxide systems with unique structural and chemical properties [11,12]. Investigation of Mn-containing mixed oxides derived from LDH precursors concentrated on layer-doped materials [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27], while only few studies addressed the use of LDHs containing manganese species in the interlayer [28][29][30][31][32][33].…”

Optimizing the synthesis of cobalt-based catalysts for the selective growth of multiwalled carbon nanotubes under industrially relevant conditions

“…For example, Rao et al [19] synthesized CNTs from methane over reduced Mg 1-x Co x Al 2 O 4 (x = 0.1 -0.4) spinel catalysts with high yields and superior qualities. Co-and Mn-based mixed oxides were used in various catalytic reactions, such as the Fischer-Tropsch synthesis [20][21][22], the decomposition of nitrous oxide [23,24], and the oxidation of volatile organic compounds [25]. As an effective promoter, Mn can significantly enhance the performance of Co catalysts.…”
