Microwave aided and plant reduced gold nanoparticles as talented dye degradation catalysts

Green alternatives prevail over hazardous and expensive pathways of nanoparticle synthesis. This study reports eco-friendly manufacturing of gold nanoparticles by microwave assistance. The water-soluble organic constituents of the tropical herb Elephantopus scaber function as the three-electron donor and the aggregation preventer. XRD spectra certied fcc crystal lattice, and the TEM images supported mixed spherical and triangular geometries of the nanoparticles with an average particle size of 18:97 5:86 nm. Ecological relevance of the gold nanoparticles lies in their ability to degrade methylene blue and methyl orange. The catalytic capacity of the gold nanoparticles is exploited for the reduction of 4-nitrophenol. Large-scale production of gold nanoparticles in an easy manner using renewable sources improves the 'green' signicance of the present synthesis.
