Synthesis and intracrystalline oxidation of nitrite-intercalated layered double hydroxides

Nitrite Reduction by Biogenic Hydroxycarbonate Green Rusts: Evidence for Hydroxy-nitrite Green Rust Formation as an Intermediate Reaction Product

“…These interlayer spacing are assigned to the incorporation of nitrite ions in the interlayer space of green rust, suggesting the formation of an hydroxy-nitrite green rust, GR(NO 2 ), a new type of green rust 1. The same d 003 and d 006 spacing values of 7.8 and 7.9 Å were assigned to nitrite ions incorporation in the interlayer region of MgAl-NO 2 and NiAl-NO 2 LDHs . Similar Bragg peaks were observed in experiment #2 performed with the same bio-GR(CO 3 ) F (Figure a–c).…”

“…The same d 003 and d 006 spacing values of 7.8 and 7.9 Å were assigned to nitrite ions incorporation in the interlayer region of MgAl-NO 2 and NiAl-NO 2 LDHs. 38 5d). These results show that the oxidation of small bio-GR(CO 3 ) F particles was faster than that of large bio-GR(CO 3 ) F particles.…”

DFT simulation of Mg/Al hydrotalcite with different intercalated anions: Periodic structure and solvating effects on the iodide/triiodide redox couple

“…The importance of HT in so many fields of chemistry and chemical engineering has motivated several recent structural studies of hydrotalcite with different composition and different intercalated anions [12,13,[18][19][20][21][22][23][24][25][26]. Also organic anions, in some cases quite large, have been successfully intercalated, confirming the high flexibility of HT layered structure [27].…”

Synthesis of 3R1and 1H Polytypes of Sulfate-Intercalated Layered Double Hydroxides (LDHs) by Postintracrystalline Oxidation and Simultaneous Intercalation-Oxidation of Thiosulfate

“…Hence, a synthetic method for preparing different polytypes of LDH would be of considerable interest. In the recent past, we have been studying the intracrystalline reactions of the intercalated inorganic anions in the interlayer of anionic clays. , While studying the intracrystalline oxidation of thiosulphate intercalated LDHs to sulfate intercalated LDHs, we found that 3R 1 and 1H polytypes of the products could be obtained when the conditions of the intracrystalline reactions were slightly modified.…”
