Scavenging Radionuclide by Shapeable Porous Materials

Nuclear energy is a competitive and environmentally friendly low-carbon energy source. It is seen as an important avenue for satisfying energy demands, responding to the energy crisis, and mitigating global climate change. However, much attention has been paid to achieving the effective treatment of radionuclide ions produced in nuclear waste. Initially, advanced adsorbents were mainly available in powder form, which meant that additional purification processes were usually required for separation and recovery in industrial applications. Therefore, to meet the practical requirements of industrial applications, materials need to be molded and processed into forms such as beads, membranes, gels, and resins. Here, we summarize the fabrication of porous materials used for capturing typical radionuclide ions, including UO22+, TcO4-, IO3-, SeO32-, and SeO42-. The radionuclide ions pose multiple hazards to the environment and human beings, and their adsorbents in powder form have numerous drawbacks and are not adequate for practical industrial applications. This concept introduces various ways of shaping of porous materials as well as their applications in treating typical radionuclide ions (UO22+, TcO4-, IO3-, SeO32-, and SeO42-). image
