The chemical modification and self-assembly capability of fullerenes offer advantageous conditions for tailoring Fe/N-doped carbon-based catalysts. However, their strong π–π stacking tendency may partially restrict metal loading and the generation of active Fe species. Therefore, how to utilize the distinctive features of fullerenes to precisely regulate and optimize Fe–N active sites along with their local coordination environment remains challenging. In this work, water-soluble C 60 (wsC 60 ) was synthesized via a facile interfacial oxidation process. The presence of –OH on the C 60 cage may strengthen its binding affinity with Fe 3+ ion and effectively modulate the incorporation of Fe/N into the C 60 -derived carbon electrodes. By varying the wsC 60 /Fe 3+ mixing ratios followed by pyrolysis under NH 3 , we obtained Fe/N-doped carbons (FeN@wsC 60 -900) with distinct Fe/N-doping states, including FeN 4 , O–FeN 4 /Fe cluster, and FeN 4 /Fe cluster. The abundant –OH in wsC 60 also promoted the formation of a highly porous network, enhancing active site accessibility. The resultant FeN@wsC 60 -900 exhibited excellent oxygen reduction reaction (ORR) activity, outperforming both conventional C 60 -derived carbons and commercial Pt/C. Structural characterizations and density functional theory (DFT) simulations revealed that the O-coordinated Fe–N 4 with adjacent Fe cluster could optimize the coordinate geometry and adsorption energies of key ORR intermediates.

The development of efficient, non-precious metal catalysts for renewable energy applications is a critical step toward sustainable power generation. This research presents and develops a simple preparation method to prepare composite catalysts based on metal phthalocyanines (MPcs) and fullerene-C 60 to improve the catalytic performance of oxygen reduction reactions (ORR) in direct lignin fuel cells ( DLFC). Electrochemical tests revealed that the FePc-C 60 catalyst demonstrated excellent catalytic performance in the ORR, with a half-wave potential (E 1/2 ) of 0.81 V, which was similar to the 0.82 V of Pt/C. Furthermore, the FePc-C 60 catalyst exhibited a near 4-electron transfer reaction mechanism, with a limiting current density of 3.9 mA cm −2 and H 2 O 2 yield below 4 %. The Tafel slope measured at 31 mV dec −1 , which was lower than the 49.6 mV dec −1 observed for the Pt/C, implying that the catalyst achieves a higher reaction rate at lower potentials. In fuel cell applications, compared to Pt/C, DLFC with FePc-C 60 as the cathode catalyst exhibited a higher maximum power density (590 mW m −2 ), surpassing Pt/C (381 mW m −2 ). This work successfully constructed an efficient and stable non-precious metal catalyst, offering a new perspective for the development of non-precious metal catalysts and high-value utilization of lignin.

Three kinds of carboxyfullerenes, La@C82-COOH, C60-COOH and C70-COOH, were used to modify gold electrodes. The electrochemical behavior of dopamine (DA) at the carboxyfullerenes modified electrodes was studied using the cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods. The C70-COOH modified electrodes performed the best among them. Under the optimal conditions, linear CV and DPV responses to DA concentration from 1 μmol/L to 13 μmol/L were observed, and the detection limit of DA was 1×10−2 μmol/L in the presence of 10 μmol/L uric acid (UA). The practical analytical utilities of the C70-COOH modified electrodes were demonstrated by the determination of DA HCl in the real samples of dopamine hydrochloride injection (DHI). Moreover, the modified electrodes exhibited good reproducibility and sensitivity, demonstrating its feasibility for analytical purpose.

C 60 modified Cr 2− x Fe x O 3 nanostructure photocatalysts were successfully synthesized by a simple absorbing process and employed in the photocatalytic H 2 evolution. The as-prepared C 60 –Cr 2− x Fe x O 3 nanocomposites exhibits significantly enhanced photocatalytic activity for photocatalytic H 2 evolution without any noble metal. It is shown that the photoinduced electrons achieve high migration efficiency on the interface C 60 and Cr 2− x Fe x O 3 , which is generated by the intense interaction of C 60 and Cr 2− x Fe x O 3 with conjugative three-dimensional π-system. A possible mechanism was proposed and supported by the PL emission spectrum technique and transient photocurrent responses.

Tri-component nanostructures of C 60 / m -xylene/thiophene were synthesized via a solvent-induced self-assembly method and characterized by SEM, TEM , XRD , FT-IR, and Raman. The shapes of nanostructures were dependent on the concentration of C 60 , the volume ratio of thiophene to m -xylene, and the volume ratio of mixture solvent to isopropanol. High-resolution TEM image and SAED pattern revealed that twisted nanorods of C 60 were single crystals and had an hcp structure. The EDX and FT-IR analysis confirmed the existence of thiophene. The results indicated that the twisted nanorods consisted of pristine C 60 , m -xylene, and thiophene molecules. In addition, thiophene molecules were assumed to partially replace m -xylene molecule in the C 60 / m -xylene lattice. Such tri-component nanorods of C 60 are ideal building blocks for fabricating novel nanodevices .

Synergistic Pd 1 and Pd NC on C 60 enable highly efficient alkene cyclopropanation. • Competitive electron effects from Pd SAs reduced the valence of Pd NCs. • C 60 served as electron buffer stabilized multiple reaction intermediates. • Competitive electron effects lower the reductive elimination energy barrier. • Product shows higher density and energy than JP-10 for aerospace fuels. Cyclopropane structure, possessing the highest intrinsic ring-strain, are pivotal structural motifs in biomedicines and energy materials. However, their precise and efficient synthesis remains a persistent challenge, primarily due to insufficient catalytic activities that hamper the formation of key metal carbenoid intermediates and lead to the low selectivity. Herein, we report a synergistic C 60 /Pd 1+NC catalyst, uniquely integrating Pd single atoms (SAs) and nanoclusters (NCs) on the C 60 , for the highly efficient and selective cyclopropanation of alkenes. The C 60 /Pd 1+NC catalyst significantly outperforms its single-component counterparts (C 60 /Pd 1 and C 60 /Pd NC ), achieving exceptional alkene conversion (99.6%) and selectivity (86.0%). Comprehensive XAFS analysis and DFT calculations elucidated Pd C bonds were formed between Pd and the C 60 framework. The competitive electron effect from Pd SAs reduced the valence of Pd NCs to promote the dissociation of CH 2 N 2 . C 60 served as electron buffer stabilized multiple reaction intermediates. These two aspects decreased the energy barrier of reductive elimination of palladocyclobutane (31.5 → 25.6 kcal/mol), which dramatically enabled the highly efficient cyclopropanation. The obtained diadduct has the higher density (0.99 g/cm 3 ) and volumetric calorific value (42.69 MJ/L) than the typical JP-10, which could be applied for high-energy aerospace fuel. This work not only provides a powerful catalytic strategy for constructing strained three-membered rings but also gains fundamental insights into the synergistic mechanism in hybrid single-atom/nanocluster systems.

Hydroxylated C 60 Fullerene (Fullerol) induced photochemical production of reactive oxygen species (ROS, e.g. singlet oxygen ( 1 O 2 ) and hydroxyl radical ( OH)) is a slow process, and the role of its surface groups other than high water-solubility is still lack of investigation. In this study, we demonstrate Fullerol can promote Fe(III)/Fe(II) cycles to degrade dimethyl phthalate (DMP) in Fe(III)/H 2 O 2 Fenton system as both an electron donor and an electron-transfer mediator. At acidic condition, the formation of carbonyl and carboxyl via pinacol rearrangement and subsequent keto-enol isomerization can produce cage-opened structure of Fullerol, resulting in the pH-dependent formation of Fe(III)-Fullerol complex. Two pathways of Fe(II) recovery via intramolecular electron transfer of Fe(III)-Fullerol complex to enhance Fe(III)/H 2 O 2 Fenton oxidation were proposed: 1) Fullerol direct reduces Fe(III) into Fe(II) as an electron donor in dark, and it was strongly enhanced under visible light irradiation; 2) Fullerol mediates electron transfer from electron donor (e.g. hydrogen peroxide and organics) to Fe(III) in visible light condition. Furthermore, DMP degradation pathway was proposed based on variation of main intermediates.

Rational design and modification of the all-carbon fullerene cages to meliorate their nature of hydrophobicity is critical for biomedical applications. The outstanding electron affinity of fullerenes enables them to effectively eliminate reactive oxygen species (ROS), the excess of which may lead to health hazards or biological dysfunction. Herein reported is a facile, mild, and green approach to synthesizing the favorable water-soluble C60nanoparticles capable of ROS-scavenging by combining the mussel-inspired chemistry with the Michael addition reaction. Various characterization techniques, including Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectra (XPS), thermogravimetric analysis (TGA), transmission electron cryomicroscopy (Cryo-TEM), and dynamic laser scattering (DLS) were carried out to confirm the satisfactory preparation of the hybrid C60-PDA-GSH nanoparticles, which exhibited apparent scavenging capacity of DPPH and hydroxyl radicals in vitro. Additionally, the biocompatible C60-PDA-GSH nanoparticles entered into cells and displayed a universal cytoprotective effect against oxidative press induced by H2O2in four kinds of human cells at a low concentration of 2 μg/mL. The ease and versatility of the strategy present in this work will not only trigger more fullerene-based materials by the immobilization of diverse functional molecules, but will also extend their possible applications.Keywords:water-soluble fullerene nanoparticles;mussel-inspired chemistry;reactive oxygen species scavenging;cytoprotective effect

Carbon-based perovskite solar cells (PSCs) without hole transport layer (HTL) have shown great prospect for practical applications because of their high stability and low cost. However, almost all of the carbon based PSCs reported so far are fabricated using titanium dioxide (TiO2) as the electron transport layer (ETL) that requires a rather high-temperature sintering process (500 °C). Moreover, they also suffer from obvious voltage–current hysteresis and conspicuous performance decline under operating conditions. Herein, we report a new type of low-temperature all carbon based PSCs using solution-processed hexamethonium bromide (HMB)-doped C60 as ETL, which achieved a high power conversion efficiency (PCE) of over 16% without the above-mentioned hysteresis. It is shown that doping of C60 with HMB carries several outstanding advantages, including faster charge transport, enhanced electron mobility, and the decreased electron trap density. More encouraging is the remarkable stability of the PSCs fabricated with HMB-doped C60 ETL, which can maintain nearly 90% of their initial performance after continuous operation for 338 hours at their maximum power point under one sun illumination in ambient air.

Incorporating n-type fullerene derivatives into the perovskite layer affording bulk heterojunction (BHJ) perovskite solar cells (PSCs) is an effective strategy to passivate trap states, consequently reducing the current–voltage hysteresis and improving the device performance. Herein, we report the synthesis of a novel pyridine-functionalized fullerene derivative (C60-PyP) via a 1,3-dipolar cycloaddition reaction, and the unambiguous determination of its molecular structure by X-ray single crystal diffraction. Upon incorporating C60-PyP as an additive with an optimized doping ratio of 0.13 wt% into the CH3NH3Pbl3 (MAPbI3) perovskite precursor, the regular-structure bulk heterojunction PSC devices exhibit a best power conversion efficiency (PCE) of 19.82%, which is dramatically enhanced relative to that of the control devices (17.61%). The C60-PyP additive provides heterogeneous nucleation sites, leading to the decrease of the nucleation Gibbs free energy and consequently enlarged grain size and improved crystallization of the MAPbI3 perovskite film. Besides, incorporation of C60-PyP results in enhanced crystalline orientation as confirmed by grazing-incidence X-ray diffraction (GIXRD) measurements. Meanwhile, the coordination interaction between the N atom of the pyridine moiety within C60-PyP and the Pb2+ ion within MAPbl3 leads to the passivation of the trap states of the perovskite layer, jointly contributing to the improved device performance and markedly suppressed current–voltage hysteresis. Moreover, the ambient stability of the devices is improved upon C60-PyP incorporation due to the hydrophobic nature of the C60-PyP molecule, which presumably resides at the grain boundaries.

Carbon nanomaterial is a momentous field of current biomedical research. However, extensive exploration is still required to endow carbon nanomaterial with both antibacterial properties and biological safety. In this study, fullerenol and calcium ions were synthesized into C 60 (OH) n -Ca nanoparticles through an electrostatic self-assembly strategy. Morphological and chemical analyses revealed that the C 60 (OH) n -Ca nanoparticles contained 4.52 at.% Ca, with a minimum size of approximately 10 nm. The electrostatic self-assembly did not alter the chemical structure of the fullerenol. The photodynamic antibacterial effect of the C 60 (OH) n -Ca nanoparticles was concentration-dependent, showing antibacterial rates of 94 % and 96.6 % against Escherichia coli and Staphylococcus aureus at a concentration of 100 μg/mL, while the antibacterial effect was unsatisfactory under dark conditions. Additionally, C 60 (OH) n -Ca nanoparticles promoted the proliferation of MC3T3-E1 cells, demonstrating desirable biological safety. The C 60 (OH) n -Ca nanoparticles synthesized in this article achieved a balance between antibacterial and cytocompatibility, thus possess potential applications in biomedical fields.

Low-dimensional nanocarbons such as fullerenes are important nano-bio model systems. Their non-covalent interactions with nucleic acid building blocks can enable molecular recognition and alter photophysical behavior, but the structural-activity relationship between nucleobases molecular structure and spectroscopy remains unclear. Here, steady-state photoluminescence (PL) spectroscopy and quantum chemical calculations were used to study C60 adsorption with five nucleobases (A, C, G, T, and U) in dimethyl sulfoxide. C60 shows a visible PL band at ∼409 nm under 301 nm excitation. Equal concentrations of nucleobases markedly enhance C60 emission with minor shifts, following T > U > A > G > C. Density functional theory (DFT) predicts stable π-stacking-like complexes with separations of ∼3.3 Å and binding energies of −0.23 to −0.38 eV. Reduced density gradient analysis reveals dispersion-dominated attraction, consistent with physisorption. Time-dependent DFT indicates that low-energy singlet excitations remain mainly localized on C60, while adsorption-induced symmetry breaking gives these states weak oscillator strength, explaining the enhanced emission. Correlation relationship for the molecular orbital transition was established, and a quantitative assessment and transition contribution were provided based on the orbital transition diagrams. These results clarify fullerene-nucleobase recognition and support adsorption-enhanced fluorescence as a probe of base-dependent interactions.
