One-step synthesis of phospho-rich, silica-enhanced chitosan aerogel for the efficient adsorption of uranium(VI).

In this study, an amorphous silica reinforced, phosphoric-crosslinked chitosan foam (P-CTS@SiO) was prepared. The introduction of amorphous silica not only increased the affinity of the adsorbent for uranium, but also improved the stability of the material. The number of active sites of P-CTS@SiO was increased by the introduction of phosphate groups.

Integration of high visible-light-driven ternary dual Z-scheme AgVO-InVO/g-CN heterojunction nanocomposite for enhanced uranium(VI) photoreduction separation.

With deepening application of nuclear power technology, the problem of water ecological environment pollution caused by uranium (U(VI)) is becoming increasingly serious. Photoreduction separation of U(VI) on photocatalysts is considered as an effective strategy to solve uranium pollution. In this work, a novel ternary dual Z-scheme AgVO-InVO/g-CN heterojunction (Z-AIGH) nanocomposite with high surface area (73.

Ultralow-refractive-index optical thin films built from shape-tunable hollow silica nanomaterials.

Shape-tunable hollow silica nanomaterials, including hollow silica nano-spheres and nano-tadpoles, were synthesized with a one-step soft-templating method. A possible particle growth mechanism was proposed. Films were built from these shape-tunable hollow silica nanomaterials with refractive indices as low as 1.
