Embodiment

[0012] In a beaker, 1 gram of hydrogen-form strong-acid cation-exchange resin is added to 60 milliliters, 0.2M of silver nitrate solution, and vibrated on a shaker for 90 minutes, silver ions are exchanged with hydrogen-form strong-acid cation-exchange resin, and then filtered; The filtered cation exchange resin was dried in an oven at 80° C. for 7 hours to remove moisture; then it was illuminated by a 300W high-pressure mercury lamp for 60 minutes to obtain 1.4 grams of Ag / ion exchange resin composite material. Measurement results: The prepared Ag / ion exchange resin composite material was analyzed by the American Thermo ESCALAB 250 photoelectron energy spectrometer to analyze the valence state of Ag on the surface of the ion exchange resin composite, and the XL30 scanning electron microscope of Philips Company in the Netherlands observed the surface morphology of the microspheres. show: by figure 1 It can be seen that the prepared Ag / ion exchange resin composite material has ...

Abstract

The invention relates to an Ag / ion exchange resin composite material which is characterized in that: cation exchange resin is added into an AgNO3 solution to ensure that Ag<+> is adsorbed on the cation exchange resin and the Ag / ion exchange resin composite material can be obtained after the Ag<+> is reduced to Ag particles by using ultraviolet light. The Ag / ion exchange resin composite material is mainly composed of the cation exchange resin, the Ag particles and a little Ag<+> and is of a spherical structure with a diameter about between 400-1200 micrometers. The Ag simple substance particles with sizes between 1-180nm are mainly distributed on the surface of the cation exchange resin. The Ag / ion exchange resin composite material has the catalytic and antibacterial actions of the Ag nanometer particles and the adsorption effect of the cation exchange resin, and has the advantages of simpleness in preparation process and low cost, and therefore the composite material can be used for many fields such as industrial catalysis, photocatalysis, antibacterial materials and the like.

Description

(1) Technical field: [0001] The invention relates to an Ag composite material, in particular to an Ag / ion exchange resin composite material. (two) background technology: [0002] In recent years, Ag and its composites have been one of the research hotspots in materials science and chemistry because of their catalytic and antibacterial properties. In industry, Ag composite materials can be used as industrial catalysts, catalytic electrodes for fuel cells, and various antibacterial materials. "China Environmental Science" 2000, No. 5, 473-476 pages reported that Zhu Tianle and others prepared Ag / Al 2 o 3 Catalyst, and for the selective reduction of NO by hydrocarbons. Chinese patent (CN1395829) discloses a nano-silver antibacterial powder with algae as a carrier and a preparation method thereof. Nano-silver particles are firmly adsorbed in algae cavities or empty cells, and the particle size is 1-100 nanometers. However, due to the existing Ag composite materials, there ar...
