Photocatalytic anti-biofouling coatings with dynamic surfaces of hybrid metal-organic framework nanofibrous mats for uranium (VI) separation from seawater

Uranium extraction from seawater: material design, emerging technologies and marine engineering

“…Incorporation of antimicrobial components that can actively kill the bacteria stained on the surface of the material, or inhibit the growth, reproduction and survival of bacteria into adsorbents is a common strategy for biofouling control, which is often referred to as an ''attacking'' strategy. In this regard, various antibacterial materials such as inorganic metal nanoparticles, [204][205][206][207][208][209] antibacterial antibiotics, 210 antimicrobial polymers, 127,128,140,[211][212][213][214][215][216][217][218][219][220][221][222] natural biological entities, 183,[223][224][225][226] antimicrobial enzymes 227 and photo-responsive antibacterial materials [228][229][230][231][232][233][234][235] have been introduced into uranium adsorbents to endow them with inherent antibacterial properties.…”

Robust and multifunctional natural polyphenolic composites for water remediation

“…12f). 181 Owing to the release of zinc ions and generation of reactive oxygen species from TA/ZIF-8 coating, the nanofibrous membrane exhibited high antibacterial and anti-algae activities, dynamic self-renewing surface and escorted a long service life of 25 day for effective uranium adsorption in natural seawater.…”

Amidoxime-Based Polymer Microspheres with High Selectivity for Uranium from Saline Lake Brine

“…The total amount of uranium resources in seawater is up to 4,500,000 kt, which is nearly 1000 times higher than those of traditional land uranium resources . The research on extracting uranium from seawater has a history of nearly 60 years. − Researchers have developed many functional groups adsorbing uranium, − and amidoxime (AO) is a typical representative. − However, it is empirically believed that the AO adsorption materials are difficult to solve the problem of metal ion selectivity, especially under the interference of vanadium . Using polyacrylonitrile (PAN) as a raw material, Wang et al prepared a mixed sponge modified by amidoxime and cyclic imide dioxime, which was applied to the extraction of uranium from natural seawater.…”
