Summary: This study investigates the influence of support materials on the reactivity of nickel-based catalysts in the production of carbon nanotubes from polyethylene. The results reveal that the Ni/Al2O3 catalyst shows the highest carbon material yield due to its unique structural characteristics. In contrast, the Ni/TiO2, Ni/ZrO2, and Ni/Nb2O5 catalysts exhibit poor performance in terms of carbon nanotube formation.

Summary: With the development of power grid system, the problem of increasing waste cable has started to affect our daily lives. This study investigates the pyrolysis behavior of polyethylene (PE), which is the main material source of cable sheath, to find solutions for waste cable accumulation and to promote the recycling of waste PE plastic. The study finds that H-Zeolite Standard Oil Corporation of New York (Socony) Mobil-Five (HZSM-5) is the most suitable and efficient catalyst among three types, and discovers a new pyrolysis path. Furthermore, the study evaluates the thermal hazard and fire safety performance of cable sheath, providing valuable guidance for future PE pyrolysis and combustion experiments as well as reference for the recycling process design of waste cable sheath and plastics.

Summary: The utilization of renewable raw materials in industrial manufacturing and the capture of carbon can reduce the carbon footprint. We developed a pyrolysis-based process to produce biogenic multi-walled carbon nanotubes (MWCNTs) and H-2 from biomass. We found that the conversion of hydrocarbon compounds into MWCNTs and H-2 is affected by the release of CO2 during biomass decomposition. Capturing CO2 with a calcium sorbent can improve the pyrolysis gas and enhance the production of MWCNTs and H-2.

Summary: This work presents a new concept of C-DPyR, an energetically self-sustaining pyrolysis reactor, as an alternative to convert polyethylene waste into wax. The wax was characterized using TGA and DSC to study its thermal behavior and perform kinetics computations. ATR-FTIR identified the functional groups in the waxes. The experiments with high thermal energies resulted in a significant amount of gas production, indicating sufficient heat for pyrolysis. Kinetic analyses using isoconversional methods were performed to determine the kinetic triplets of wax pyrolysis.

Summary: In this study, the effect of hydrogen on the growth of single-walled carbon nanotubes in the aerosol chemical vapor deposition process was investigated. It was shown that hydrogen inhibits the pyrolysis of ethylene, extending the synthesis parameter window. Three different regimes of hydrogen effect were distinguished: pyrolysis suppression at low concentrations, surface cleaning/activation promotion, and surface blockage/nanotube etching at high concentrations. This detailed study contributes to understanding the complex role of hydrogen and its impact on the synthesis of single-walled carbon nanotubes.

Summary: The design of efficient catalysts is crucial for plastic waste recycling. In this study, high-dispersion nickel-based catalysts were developed using the ethylene glycol assisted impregnation method for the production of carbon nanotubes from pyrolytic catalysis of polyethylene. The addition of ethylene glycol promoted the dispersion of nickel metal, resulting in smaller NiO particle size and enhanced conversion of polyethylene into carbon nanomaterials. This study provides promising directions for the preparation of high-performance catalysts for the production of high-value chemicals from plastic waste.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.

Summary: A detailed understanding of the interaction between molecules and two-dimensional materials is crucial for incorporating functional molecular films into next-generation 2D material-organic hybrid devices. This study compares the energy level alignment of different-sized fullerenes on a Moire superstructure and finds that C-84 fullerenes can be either neutral or negatively charged depending on slight variations of the electrostatic potential. This discovery suggests a new path to achieve ambipolar charge transfer without overcoming the electronic gap of fullerenes.
