Abstract
Gold nanoparticles were densely deposited on the surface of C60 microcrystals having a variety of unique shapes. C60 microcrystals were prepared by a conventional liquid–liquid reprecipitation method. The shapes of C60 microcrystals, such as bipyramid, belt, disc, and rod, were achieved by carefully adjusting the solvent species in the liquid–liquid reprecipitation process. Gold nanoparticles were directly deposited on C60 microcrystals without adding any conventional reducing agent but only heating HAuCl4 in C60 microcrystals ethanol dispersion containing CS2. Scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, powder X-ray diffraction, absorption spectroscopy, and X-ray photoelectron spectroscopy studies were conducted to characterize the gold–C60 heterostructure. The gold–C60 heterostructure showed charge transfer behaviour where gold was an electron donor and C60 was an electron acceptor. C60 microcrystals-supported gold nanoparticles also showed catalytic activity in reduction of p-nitrophenol at room temperature. A facile reduction mechanism was suggested for gold deposition on the surface of C60 microcrystals.
