Gold nanoparticles to be added in silver nanowires for enhancing visible light irradiation
21 June 2010A Researcher has thought of decorating silver chloride nanowire with that of gold nanoparticles and has studied its affect of various chemical and physical properties of the material. Nanoscientist Yugang Sun at US Department of Energy’s (DOE) Argonne National Laboratory has created visible light catalysis using the method.
Silver nanowires have been continuously studied for various parameters as per the requirement of their applications optoelectronic devices and transparent conductive electrodes. These silver nanowires were first converted by the researcher into semi-conducting silver chloride nanowire and gold nanoparticles were added later into it.
The conventional silver nanoparticles are photocatalytic to limited to ultraviolet and blue light wavelenghths, however gold nanoparticles containing silver chloride are photolytic to entire visible light. Yugang found that the new material has significantly different properties and found that once you allow polluted water to flow through it, the organic molecule destroyed. These organic molecule were found destroyed with visible irradiation from sun or any other source of light such as fluorescent light bulbs.
