Rapid and One‐Step Transformation of LiAlH4 to Inorganic and Organic Anion Intercalated Li‐Al Layered Double Hydroxides

“…The balance of this extra positive charge is fulfilled by an interlayer anion (Figure ). Li‐Al hydrotalcite has been synthesized earlier by co precipitation, salt imbibition, reaction of hydrated alumina gel with LiOH in alcoholic medium, sol‐gel and mechanical activation of Al(OH) 3 with various lithium salts . Exchange chemistry of LiAl 2 (OH) 7 · 2H 2 O with other inorganic anions such as chloride, nitrate, carbonate as well as with organic dicarboxylate anions have also been probed .…”

“…Li-Al hydrotalcite has been synthe- sized earlier by co precipitation, salt imbibition, reaction of hydrated alumina gel with LiOH in alcoholic medium, sol-gel and mechanical activation of Al(OH) 3 with various lithium salts. [9][10][11][12][13] Exchange chemistry of LiAl 2 (OH) 7 ·2H 2 O with other inorganic anions such as chloride, nitrate, carbonate as well as with organic dicarboxylate anions have also been probed. [14][15][16][17] With the demonstration of using Li-Al LDH for the removal of toxic anions such as fluoride, arsenate and the possibility of their use in storing and releasing drugs, agrochemicals and vitamins at designated places on suitable activation, search for a facile and rapid synthesis of this system is highly justified.…”

Phase Chemistry for Hydration Sensitive (De)intercalation of Lithium Aluminum Layered Double Hydroxide Chlorides

“…Even though it is usually reported as an integer, it is actually an approximation of the experimental determination . In most cases, the determined hydration number is far from the integer, and varies from ∼0 to 3.5. ,,,,− Up until now, when LADH-Cl is used as a lithium sorbent, if the hydration number of LADH-Cl will change, how it changes and to what extent it can change are still blind spots. Second, the Al:Li molar ratio in LADH-Cl is also volatile and varies from ∼2 to 3.5.…”
