锂作为新能源核心战略资源，其高效提取技术开发迫在眉睫。针对传统盐湖提锂动力学局限，通过低温水热法(40～160℃)构筑H_2Ti_3O7型钛基锂离子筛。80℃合成H_2Ti_3O7(HTO80)比表面积达422.0 m2·g-1,在pH=6.5时对Li+吸附容量14.1 m2·g-1,10 min即达平衡容量93.6%,5次循环后容量保持78%。吸附符合准二阶动力学及Langmuir模型，证实通过H+/Li+离子交换实现特异性吸附，且具有较好Li+选择性。该研究为高效盐湖提锂提供了新思路，H_2Ti_3O7在提锂材料中表现出巨大潜力。
Abstract：As a core strategic resource for new energy applications, the development of efficient lithium extraction technologies is urgently needed. This study addresses the kinetic limitations of traditional salt lake lithium recovery by constructing an H_2Ti_3O7-type titanium-based lithium-ion sieve(LIS) through low-temperature hydrothermal synthesis(40—160 ℃). The HTO80 sample synthesized at 80 ℃ exhibits a specific surface area of 422.0 m2·g-1 and delivers a Li+ adsorption capacity of 14.1 mg·g-1 at pH 6.5, achieving 93.6% of its equilibrium capacity within 10 minutes while retaining 78% capacity after five adsorption-desorption cycles. The adsorption process aligns with pseudo-second-order kinetics and the Langmuir monolayer model, confirming selective H+/Li+ ion exchange as the dominant mechanism, with exceptional Li+ specificity. This work provides a novel strategy for high-efficiency salt lake lithium extraction, demonstrating the significant potential of H_2Ti_3O7-based materials in lithium recovery technologies.
