Catalytic Activity for Reduction of 4-Nitrophenol with [C₆₀]Fullerene Nanowhisker-Silver Nanoparticle Composites

Abstract

Silver nanoparticle solution was prepared by the addition of silver nitrate (AgNO 3 ), trisodium citrate dihydrate (C 6 H 5 Na 3 O 7 ·2H 2 O), sodium borohydride (NaBH 4 ), cetyltrimethyl ammonium bromide ((C 16 H 33 )N(CH 3 ) 3 Br), and ascorbic acid (C 6 H 8 O 6 ), which was subsequently added to distilled water. The resulting solution was subjected to ultrasonic irradiation for 3 h. [C 60 ]fullerene nanowhisker-silver nanoparticle composites were prepared using C 60 -saturated toluene, silver nanoparticle solution, and isopropyl alcohol by the liquid-liquid interfacial precipitation (LLIP) method. The product of [C 60 ]fullerene nanowhisker-silver nanoparticle composites was con rmed by x-ray diffraction, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy. The activity of [C 60 ]fullerene nanowhisker-silver nanoparticle composites as a catalyst was characterized by the reduction of 4-nitrophenol by UV-vis spectroscopy.

Preparation of C60 Fullerene Nanowhisker–CuS Nanoparticle Composites and Photocatalyst for Rhodamine B Degradation under Blue Light Emitting Diode Irradiation

“…In addition, CuS nanoparticles have shown outstanding photodegradation and quick dye adsorption capabilities for organic dyes in aqueous solution [2]. Recently, interest in C 60 fullerene nanowhiskers has increased due to their distinct chemical and physical characteristics, as well as potential uses in materials like catalysis and photocatalysis [18][19][20][21][22][23][24][25]. The C 60 fullerene nanowhiskers of the needle-like crystals were prepared by the liquid-liquid interfacial precipitation (LLIP) method using a C 60 -saturated toluene and isopropyl alcohol [26].…”
