摘要：
This work reports a facile solvothermal synthesis of hierarchical flower-like Na2Ti3O7 structures with fast and high methylene blue adsorption capacity. A mesoporous architecture of Na2Ti3O7 with a surface area of 159.63 m(2)-g(-1) was produced under mild alkaline conditions (2 M NaOH) and a short reaction time (8 h). Interestingly, methylene blue adsorption equilibrium on the Na2Ti3O7 powders was achieved in a short time of 10 min. The pseudo-second-order kinetic model and the Langmuir isotherm model described the adsorption mechanism. The synthesized Na2Ti3O7 powders have interesting features that highlight their suitability for environmental applications. (C) 2021 Elsevier B.V. All rights reserved.
