    Abstract Capacitive deionization (CDI) is a promising technology for removal of ions from saline water upon applying a voltage between two electrodes. In this work, chemically exfoliated MoS 2 (ce-MoS 2 ) has been explored as electrode material for CDI. The ce-MoS 2 nanosheets demonstrate a good cycling stability, high ion quality removal capacity of 8.81mg/g, and ion volume removal capacity of 16.51mg/cm 3 at 1.2V applied voltage in 400mM NaCl solution. Comparison with that of carbon materials and bulk MoS 2 , the ce-MoS 2 nanosheets remain good removal capacity even at a low concentration of 50mM salt. These results suggest that ce-MoS 2 can be a promising candidate for CDI. The sound performance of ce-MoS 2 in CDI can be attributed to the unique two-dimensional (2D) thin sheet structure of 1T phase. The large layer-to-layer space and sound electric conductivity help ion intercalation and ion transportation, and the abundant negative charges on the surface of ce-MoS 2 sheets enhance the electrostatic attraction of ion. Highlights Chemically exfoliated MoS 2 (ce-MoS 2 ) is explored as electrode material for CDI technique. Both high quality and volume specific salt removal capacity have been demonstrated. Enhanced ion intercalation, transportation and electrostatic attraction are observed. The large layer-to-layer space and abundant negative charges of the 1T phase promotes significantly the CDI process. Graphical abstract Chemically exfoliated MoS 2 (ce-MoS 2 ) has been demonstrated as excellent electrode material for capacitive deionization (CDI) technology. The large layer-to-layer space, 1T phase and the abundant negative charges on the surface of ce-MoS 2 sheets contribute significantly to the ion intercalation/transportation and electrostatic attraction of ion. As a result, both very high mass and volume specific ion removal capacities were achieved, which is especially useful for developing highly efficient CDI device with small volume and low cost in practical applications [DISPLAY OMISSION]
