“…CTAB was selected from a few surfactants, such as sodium dodecyl sulfate, sodium dodecyl benzene sulfonate, 4‐(1,1,3,3‐tetramethylbutyl)phenyl‐polyethylene glycol and polyethylene glycol sorbitan monolaurate, because it exhibits the highest stability for CNO water dispersions. These results were published in a previous study . The typical synthesis was initiated by the formation of Zn(OH) 2, which was transformed to ZnO by heating.…”

We report a facile chemical method to synthesize hybrid nanocomposites containing carbon nano-onions (CNOs) and zinc oxide or hydroxide. The structure, surface morphology, optical properties and surface area of the CNOs were characterized by X-ray diffraction, scanning electron microscopy with energy dispersive spectroscopy, transmission electron microscopy, thermogravimetric analysis, infrared and Raman spectroscopies, and adsorption/desorption N 2 techniques. For the first time, we demonstrate the fabrication of bulk heterojunction organic solar cell devices utilizing hybrid nanocomposites containing CNOs and ZnO as the electron transport layer. This configuration showed good photovoltaic performance with maximum external quantum efficiencies of 16.5 and 48.9% and power conversion efficiencies of 0.42 and 1.49% for the pristine ZnO and CNO/ ZnO (m CNO : m ZnO = 1 : 4) layers, respectively.[a] Dr.

“…Such modified CNs were used as a platform for further functionalization by thiol derivatives. For biomedical applications, CNOs were combined with five different surfactants, including hexadecyltrimethylammonium bromide (CTAB), sodium dodecyl benzene sulfonate (SDBS), sodium dodecyl sulfate (SDS), 4‐(1,1,3,3‐tetramethylbutyl)phenyl‐polyethylene glycol (Triton X‐100), and polyethylene glycol sorbitan monolaurate (Tween 20) . These composites showed long‐term stability and very high dispersion in polar solvents .…”

These composites showed long‐term stability and very high dispersion in polar solvents . In addition, it was reported that non‐covalent modification of the CNO surface using pyrene‐BODIPY, 1,4‐naphthoquinone or 9,10‐phenanthrenoquinone changes their hydrophobic properties .…”

“…CNOs and nickel hydroxide were prepared by a precipitation method with three different mass ratios of both components. After thermal annealing of CNO/Ni(OH) 2 , a composite containing CNOs and NiO with a homogeneous distribution of both components was obtained ,. The doping of composites with inorganic materials enhanced their electrochemical stability and related properties due to their pseudocapacitive characteristics.…”
