Fabrication and evaluation of effective zeolite membranes for water desalination

Asymmetric transport and desalination in graphene channels

“…The purification and desalination of seawater provide a potential key to solve this issue and thus have attracted extensive attention in recent years. [1][2][3][4] In particular, because of the advances in the nanomaterial fabrication technology, nanocomposites demonstrate a wide application in water treatment processes, exemplified by thin-film nanocomposites (TFNs), 5 carbon-based membranes, [6][7][8][9][10] zeolites, 11 and zwitterionic materials. 12,13 Such membrane-based seawater desalination has made great progress over the past decade, where the operation principle lies in the balance between salt rejection and water permeability.…”

Emerging MXene@Metal–Organic Framework Hybrids: Design Strategies toward Versatile Applications

“…Water is highly abundant on earth, but the availability of pure water is limited, as only 1% of earth’s water is suitable for drinking purposes. , The main challenge against the purification of seawater is the removal of total dissolved salts, whereas wastewater from the petrochemical and oil industries involve the separation of complex oil/water emulsions to generate fresh water. Many efforts have been already put forth for the removal of salt ions from saline water and the separation of oil/water emulsions, but still more advanced methods and strategies are highly desirable. − The use of MXene-based solar absorbing materials for water desalination was proposed in the literature, but often suffers from lack of suitable band gap for efficient light absorption, less oxidation stability, and high thermal conductivity. − The 2D MOF-based membranes have shown high potentials for wastewater treatment involving contamination removal through separating oil, but there is a shortcoming of obtaining 2D MOFs. , These bottlenecks can be overcome by developing MXene/MOF hybrids to be implemented for wastewater treatment strategies. For water desalination, recently Fan and co-workers demonstrated excellent salt removing capacity through MXene/Co-MOF hybrid-based hierarchical design .…”

Preparation and characterization of PVA‐g‐GO/PVA/PAN composite membrane for pervaporation desalination

“…To study the separation effect of the membrane on the multi-salt solution, salt solutions of different components were also used in the experiment. [48,49] The compositions of different multi-salt solutions in desalination tests are listed in Table 2.…”
