“…The results above indicated that C 60 could effectively inhibit the photocorrosion and boost the stability of CdS. Furthermore, Meng, Peng, Zhu, Oh and Zhang [56] In addition, Meng and co-workers assembled CoS/C 60 and AgS/C 60 nanocomposites for pollutant decomposition [52,119]. Superior photocatalytic efficiency was obtained in these photocatalysts after the introduction of C 60 , since C 60 is an energy sensitizer that could improve the quantum efficiency and boost charge transfer efficiency.…”

“…Typically, fullerene and MCPBA are dissolved into benzene, followed by heating reflux for hours to activated the surface of fullerene. For instance, CoS/C 60 nanocomposite was prepared by using the MCPBA-oxidized C 60 via hydrothermal method [ 52 ]. Namely, MCPBA-oxidized C 60 , CoCl 2 and Na 2 S 2 O 3 mixture water solution was heated at 150 °C for 12 h in autoclave, and the CoS/C 60 nanocomposite was obtained through filter.…”

Solar light is an inexpensive energy source making up for energy shortage and solving serious environmental problems. For efficient utilization of solar energy, photocatalytic materials have attracted extensive attention over the last decades. As zero-dimensional carbon nanomaterials, fullerenes (C60, C70, etc.) have been extensively investigated for photocatalytic applications. Due to their unique properties, fullerenes can be used with other semiconductors as photocatalyst enhancers, and also as novel photocatalysts after being dispersed on non-semiconductors. This review summarizes fullerene-based materials (including fullerene/semiconductors and fullerene/non-semiconductors) for photocatalytic applications, such as water splitting, Cr (VI) reduction, pollutant degradation and bacterial disinfection. Firstly, the optical and electronic properties of fullerene are presented. Then, recent advances in the synthesis and photocatalytic mechanisms of fullerene-based photocatalysts are summarized. Furthermore, the effective performances of fullerene-based photocatalysts are discussed, mainly concerning photocatalytic H2 generation and pollutant removal. Finally, the current challenges and prospects of fullerene-based photocatalysts are proposed. It is expected that this review could bring a better understanding of fullerene-based photocatalysts for water treatment and environmental protection.

Nanosized cobalt disulfide (CoS 2 ) particles were synthesized with 0.08 M cobalt chloride hexahydrate (CoCl 2 ·6H 2 O) and 0.2 M sodium thiosulfate pentahydrate (Na 2 S 2 O 3 ·5H 2 O) dissolved in distilled water under microwave irradiation. [C 60 ]Fullerene-CoS 2 nanocomposites were prepared with nanosized CoS 2 particles and [C 60 ]fullerene as heated by 700 o C for 2 h in an electric furnace. X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) identified the heated [C 60 ]fullerene-CoS 2 nanocomposites. Heated [C 60 ]fullerene-CoS 2 nanocomposites were investigated the activity of photocatalytic degradation as a catalyst in various organic dyes like acid yellow 23, methylene blue, methyl orange, and rhodamine B with ultraviolet light at 254 nm by UV-vis spectrophotometer.

The use of semiconductor‐based photocatalytic methods has been widespread for a range of applications, including pollution control and energy generation. However, certain analytical concerns limit the effectiveness of these photocatalysts, such as their limited light absorption capacity, physicochemical instability, and large energy band gap. To address these issues, scientists have been exploring integrating carbonaceous materials into photocatalytic systems to enhance their activity. This review focuses specifically on fullerene photocatalysts, a type of carbonaceous photocatalyst that has shown great promise in recent research. Fullerenes, which include C60 and C70, have unique properties that make them ideal for use as photocatalyst amplifiers in combination with other semiconductors or non‐semiconductors. This review summarizes recent research into the use of fullerene‐based materials for a variety of photocatalytic applications, including pollutant degradation, and hydrogen energy production. The efficacy of fullerene‐based photocatalysts is also discussed in recent breakthroughs in photocatalytic mechanisms and synthesis methods, focusing on pollution removal and hydrogen generation. Finally, the review addresses ongoing challenges and opportunities for fullerene‐based photocatalysts. The goal is to contribute to advancements in environmental protection and energy generation.
