Research Progress on New Types of H2TiO3 Lithium-Ion Sieves: A Review

The advantages of new types H2TiO3 lithium-ion sieves, including excellent adsorption performance, high-efficiency Li+-ion selectivity, reliable regeneration, environmental friendliness, and easy preparation, have attracted considerable attention. Currently, the prices lithium carbonate other related products are rapidly increasing, so use sieves to extract resources in salt lake brine has become a crucial strategy. sieve is layered double hydroxide with 3R1 sequence arrange oxygen layers. Its mechanism involves breaking surface O-H bonds formation O-Li bonds. This study provides theoretical basis for developing sieves. article also summarizes influencing factors synthesis process H2TiO3, which can seriously influence offers experimental verification preparation prepared from anatase using reasonable method show largest capacity. In addition, effective ways recycle outlined, provide guarantee its industrial application. Finally, this paper full text points out future research directions
