Catalytic Au Wool-Ball-Shaped Nanostructures Academic Article uri icon


  • New gold nanoparticles mimicking "wool-balls" were synthesized through simple, spontaneous crystallization / reduction of gold thiocyanate [Au(SCN)4-] in water, without co-addition of neither nucleating seeds, templating compounds, nor reducing agents. The Au nano wool-balls were highly uniform in size and displayed remarkable nanoribbon surface morphology. Size- and structural-modulation of the particles were accomplished through both tuning the concentration of the gold complex, as well as upon adding small quantities of organic solvents. The unique corrugated morphology and high surface area of the Au nano wool-balls enabled their use as effective catalytic substrates for methanol oxidation and nitrophenol reduction.
