N2 - The framework dimension has been proven to exert significant influence on the separation performance of molecular sieve membranes (MSMs). Compared with the flourishing research on three-dimensional (3D) and two-dimensional (2D) membranes, relevant studies on one-dimensional (1D) membranes remained rarely explored to date. In this study, well-intergrown 1D VS4 membranes were facilely prepared by in situ solvothermal growth. Among various synthetic parameters, the pH value of the precursor solution was found to play a crucial role in modulating the membrane microstructure, so that uniform and continuous 1D VS4 membrane could be obtained at the pH value of 10 in ethylene glycol-H2O (EG-H2O) binary solvent. Relying on regular interchain space and great hydrophilicity, our membrane displayed excellent dye rejection efficiency (>99.0%), thus holding great promise for energy-efficient separation.
