Herein, the C 60 /Cd 0.5 Zn 0.5 S (C 60 /CZS) photocatalysts with excellent photocatalytic performance were prepared using facile one-pot hydrothermal method. The crystal structure, morphology, photoelectric performance and photocatalytic activity of the samples were characterized by XRD, XPS, UV–Vis and electrochemistry. The catalytic degradation of pollutants under the irradiation of visible light was simulated using Rhodamine B (Rh B). The content of C 60 was changed from 0.5 to 5 wt%, and the optimal value for the photocatalytic activity was determined to be 2 wt%. The apparent degradation rate and degradation efficiency of Rh B were 0.024 min −1 and 97.5% within 140 min, which is 3.4 times that of pure CZS. C 60 /CZS exhibited excellent catalytic performance, and its photocatalytic activity was sustained even after three cycles. Moreover, electrochemical test results demonstrated that the separation and transfer of photocarriers on CZS surface were effectively improved by C 60 , thus enhancing its activity. In this study, we innovatively prepared a novel photocatalyst by combining fullerenes with sulfide solid solution for the first time, which has rarely been studied in the past. The synthetic method is simple, efficient and pollution-free. Subsequently, the catalytic degradation of Rh B experiment confirmed that the catalyst has high catalytic efficiency and stability. This experiment has practical significance not only for the catalytic degradation of Rh B but also for the application of fullerene in photocatalysis.

As a major public health issue, early cancer detection is of great significance. A field-effect transistor (FET) based on an MoS2/C60composite nanolayer as the channel material enhances device performance by adding a light source, allowing the ultrasensitive detection of cancer-related miRNA. In this work, atomic layer deposition (ALD) was used to deposit MoS2layer by layer, and C60was deposited by an evaporation coater to obtain a composite nanolayer with good surface morphology as the channel material of the FET. Based on the good absorption of C60by blue-violet light, a 405 nm laser was selected to irradiate the channel material, improving the function of FET biosensors. A linear detection window from 10 pM to 1 fM with an ultralow detection limit of 5.16 aM for miRNA-155 was achieved.Keywords:ultrasensitive detection;FET;MoS2/C60composite nanolayer

In this work, amorphous CoB has been uniformly coated on C 60 surfaces through a simple ball milling process. Accordingly their XRD , SEM and TEM measurements clarify their related composite structures. Especially, a C-B chemical bond has been found through its XPS measurement, which enhanced the composite's stability and electrochemical activity. And the following electrochemical experimental results demonstrated that the as-obtained C 60 /CoB composite had considerably high storage capacities of 602 mA h/g, which were much higher than those of individual C 60 and CoB. Furthermore their hydrogen storage processes and the mechanism have also been investigated.

This study proposed a high sensitivity optical fiber relative humidity sensor (OFHS). Besides, a fullerene derivative, C 60 -THAM, was synthesized and firstly reported as a molecule receptor in the OFHS. Compared with the widely researched carbon-based materials in OFHS, the C 60 -THAM film has abundant amino dangling bonds , hence emerges naturally as excellent receptors for water molecules. Besides, a cascaded Fabry-Perot interferometer (FPI) was fabricated in the core of single-mode fiber (SMF) without surface damage by femtosecond laser . In the OFHS, the relative humidity (RH) was measured by the Vernier effect. The working principle of the OFHS was analyzed through calculation and simulation. In the experiment, C 60 -THAM was coated on the plant fiber end. The sensitivity of the sensor is about 0.42 nm/RH as the relative humidity change from 30 % to 65 % while the optical-matter reaction length is only about 150 nm. Moreover, the sensor exhibited a stable performance as the RH was decreasing from 65 % to 30 %. The OFHS in this work is fast response and the response time for the rising and decay process was about 2.2 s and 3.2 s respectively.

trans -Porphyrin containing phenyl group at both ends was synthesized via corresponding dipyrromethanes (DPM) in the presence of TFA and DDQ. The polyethyleneglycole (PEG) chains were attached at the trans positions of ABA type porphyrinic moiety. The prepared PEGylated porphyrin (with PEG arms at the periphery) P-(PEO) 2 was self-assembled into spheres of uniform diameter while their DMF solution was dialyzed into water. Furthermore, the addition of fullerene (C 60 ) to P-(PEO) 2 caused complexation between porphyrin and fullerene which lead to interesting and trenchant morphology having worm like lateral aggregates. The assembly process and the as-prepared edifices were characterized using UV–vis absorption spectroscopy and the morphology of these assemblies was investigated using transmission electron microscope (TEM). Furthermore, the DNA binding with porphyrin aggregates has been demonstrated via electrochemical (cyclic voltammetric) response of screen printed electrodes modified . The obvious increase in redox current disclosed the intermolecular interactions of the adducts with the DNA. These studies of unprecedented adducts can further be explored for potential applications in biosensors .

Ti 3 C 2 T x MXenes with excellent metallic conductivity and flexibility have shown a promising prospect as electromagnetic interference (EMI) shielding materials. Ultrathin, hierarchical hybrid films were fabricated by using C 60 intercalating Ti 3 C 2 T x MXenes with the assistance of water-soluble γ -cyclodextrin (CD). The C 60 /CD complex was obtained by high-speed vibration milling using hydrophilic CD as dispersing agent. After thermal annealing treatment, the obtained hybrid film exhibited excellent EMI shielding (53.52±0.43 dB), hydrophobicity (water contact angle: 93.7°) and mechanical stability (over 0.9 million bending times). Taking advantage of the antioxidant of C 60 , the chemical durability of Ti 3 C 2 T x MXenes based hybrid films was also improved as expected. These results indicate that the well-designed hierarchical hybrid films with the intercalation of C 60 have promising potential for high-performance EMI shielding applications.

One-dimensional C60 nanostructures with tunable bandgaps and a wide optical absorption range are considered as potential candidates for ultraviolet/visible photodetectors. Herein, we report a low-cost visible photodetector based on C60 nanorods (NRs), which was synthesized using the liquid–liquid interfacial precipitation method. The experimental results demonstrate that the photosensitivity of C60 NR-based visible photodetectors can be enhanced significantly by coupling with Cu2O nanocubes (NCs, ∼20 nm in size). The photosensitivity of a photodetector based on the C60 NR/Cu2O NC is ∼72.5 and 40 fold higher after ratio optimization with 405 and 532 nm light illumination, respectively, which are 3.8 and 5.6 times correspondingly higher than those of pure C60 NRs. Furthermore, the energy band structure of the C60 NR/Cu2O NC heterojunction was analyzed using cyclic voltammetry to illustrate the dramatically enhanced photosensitivity. The enhanced mechanism of photosensitivity is ascribed mainly to the fact that the formation of a p/n heterojunction in the C60 NR/Cu2O hybrid strengthens the separation of photo-induced electrons/holes at the interface.

The fullerene derivative C60-CM-Cn was synthesized via a two-step reaction using fullerene (C60), curcumin (C21H18O5), and bromoalkanes (RBr) as raw materials. The structure of C60-CM-Cn was characterized by nuclear magnetic resonance (1H and 13C NMR) and high-resolution mass spectrometry (HR MS). Thermal analysis, including differential thermal analysis (DTA), vacuum stability tests (VST), thermogravimetric analysis (TG), and methyl violet experiments, along with electron paramagnetic resonance spectroscopy, was used to investigate the interaction mechanism between C60-CM-Cn and nitrocellulose (NC). The results demonstrated that there is good compatibility between C60-CM-Cn and NC, C60-CM-Cn extended the color change time of methyl violet paper by 28–47 min, reduced the gas released during the thermal decomposition of NC by 0.7–1.69 mL g−1, and decreased the heat loss rate of NC by 9.8–15.6%. Additionally, at a minimum concentration of 0.19 g L−1, C60-CM-Cn achieved a 50% removal rate of nitrogen oxides (NOx). These findings indicate that C60-CM-Cn serves as an effective antioxidant for the removal of nitrogen oxides from NC fibers, outperforming traditional stabilizers such as diphenylamine (DPA) and C2 in improving NC stability.

Graphical A unique amphiphile was prepared whereby two Dawson polyoxometalates were covalently connected to one fullerene C 60 sphere. The amphiphile shows tunable aggregation behaviour in single and binary solvent mixtures controlled by collective effects of π–π interaction, electrostatic interaction and solvophobic effect. Two-dimensional plates, solid spheres and vesicles have been observed, which represent a new class of multifunctional materials. An organic-inorganic hybrid ( 5 ) is synthesized where two Dawson polyoxometalate (POM) moieties are linked to one fullerene C 60 unit. In a POM-friendly solvent such as DMSO, DMF and CH 3 CN, 5 forms small vesicles below 100 nm at a concentration of 37.3 mg mL –1 . When the concentration decreases to 9.0 mg mL –1 , detection of aggregates becomes difficult. However, supramolecular structures with diverse morphologies can be induced upon the addition of H 2 O or toluene. In DMSO/H 2 O and DMF/H 2 O systems, plates form, which break to debris and small vesicles at high volume percentage of H 2 O. In CH 3 CN/H 2 O mixtures, solid spheres form, which fail to further evolve into other self-assembled structures. In DMSO-based binary mixtures, the type of poor solvent has a big influence on the aggregation behavior of 5 , and replacing H 2 O with toluene transfers the aggregates from plates to multilamellar and multicellular vesicles. In contrast, in CH 3 CN-based systems, the influence of the type of poor solvent is quite limited. Although the morphologies of the aggregates change a lot, their magnetic properties remain unchanged as confirmed by electron spin-resonance measurements.

Fullerene (C60) enhanced mesoporous CdS/TiO2 architectures were fabricated by an evaporation induced self-assembly route together with an ion-exchanged method. C60 clusters were incorporated into the pore wall of mesoporous CdS/TiO2 with the formation of C60 enhanced CdS/TiO2 hybrid architectures, for achieving the enhanced photostability and photocatalytic activity in H2 evolution under visible-light irradiation. Such greatly enhanced photocatalytic performance and photostability could be due to the strong combination and heterojunctions between C60 and CdS/TiO2. The as-formed C60 cluster protection layers in the CdS/TiO2 framework not only improve the light absorption capability, but also greatly accelerated the photogenerated electron transfer to C60 clusters for H2 evolution.

Fullerene (C60)-enhanced Bi2TiO4F2 hierarchical microspheres were prepared by a facile solvothermal method. Compared to the pure Bi2TiO4F2 photocatalyst, the C60/Bi2TiO4F2 samples exhibit much stronger photocatalytic performance for degrading Rhodamine B (RhB) and Eosin Y (EY) under visible light irradiation. Such greatly enhanced photocatalytic activity may be ascribed to strong combination and heterojunctions between C60 and Bi2TiO4F2, favorable for charge separation and light adsorption. Loading C60 on Bi2TiO4F2 results in a new photocatalytic mechanism (based on photo-generated hvb+ and ·O2- radicals) different from that of pure Bi2TiO4F2.

Effects of a photocatalyst, C60-modified Bi2TiO4F2, on pine kraft lignin under visible light irradiation were investigated, along with those of Bi2TiO4F2 and C60/TiO2 as references. The influences of pH, C60 mass fraction, and the initial lignin concentration on lignin conversion and yields of mono-phenolic products were investigated. Seven products were determined by GC/MS, including phenol, 2-methoxyphenol, 4-ethyl-2-methoxyphenol, 2-methoxy-4-vinylphenol, vanillin, acetovanillone, and homovanillic acid. The yields of products and lignin conversion were higher by C60/Bi2TiO4F2 than Bi2TiO4F2 and C60/TiO2. C60/Bi2TiO4F2 and C60/TiO2 were more stable than Bi2TiO4F2 upon repetitive recycling of catalyst. The effectiveness of C60/Bi2TiO4F2 declines 25%, whereas that of Bi2TiO4F2 declines 56.4% after being recycled five times. FTIR and HRTEM indicated that the deactivation of photocatalysts might be caused by lignin adsorbed on the surface of photocatalysts and the change in the crystal structure.
