Embodiment

[0075] Various embodiments of the present disclosure may be better understood by reference to the following examples, which are provided by way of illustration. The present disclosure is not limited to the examples given herein.

[0076] Fabrication of Selenium, Iron and Copper Nanoparticle Sponge

[0077] In one embodiment, metal salts or acid precursors such as ferric sulfate heptahydrate, ferric chloride, selenous acid, and copper chloride may be dissolved in the solution. A sponge material made of polyurethane, cellulose, polystyrene, polyethylene terephthalate, polypropylene or polyamide can then be soaked in this solution for a period of time to dissociate the metal ions into the sponge.

[0078] Subsequently, the sponge can be placed in a standard convection or vacuum oven at temperatures above 100°C. By placing the sponge in an oven, the water can be evaporated from the sponge, which presses the metal ions together while reducing those ions to metal or nonmetal parti...

The article further includes a plurality of metallic or non-metallic nanomaterials disposed on at least one of thesupports. Each of the plurality of metallic or non-metallic nanomaterials is directly bound to at least one of the supports.

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 476,166, entitled "POROUS NANOCOMPOSITES SORBENTS FOR MULTIPOLLUTANT CAPTURE," filed March 24, 2017, Its entire content is incorporated herein by reference. technical field [0003] The present application relates generally to porous nanocomposites and methods of making and using the same. Background technique [0004] Contaminants can be found in a variety of fluid media. Removal of contaminants may be desirable for a number of reasons. However, challenges in removing pollutants include the cost of manufacturing devices that remove pollutants and the efficiency of those devices. Contents of the invention [0005] Articles of the present disclosure include a porous scaffold structure comprising a plurality of supports. The article also includes a plurality of metallic or non-metallic nanomaterials disposed on at least one of the supports. Each of the p...
