    Density Functional Study of the Adsorption of Methanol and its Derivatives on Boron Nitride Nanotubes by Ali Ahmadi Peyghan, Maziar Noei

    Published 2013-09-01
    “…The study results showed that molecules of methanol can be chemically adsorbed on top of a sidewall B atom with an adsorption energy of −0.67 eV, which is stronger than that of carbon nanotubes. When using different derivatives of methanol, the adsorption energies and charge transfer from the adsorbate to the BNNT depending on the electron-withdrawing or electron-donating capability of the subgroups within the derivatives. …”

    The Effect of Molten Salt Composition on Carbon Structure: Preparation of High Value-Added Nano-Carbon Materials by Electrolysis of Carbon Dioxide by Yi Cheng, Liangxing Li, Lirong Xue, Jiahang Wu, Jingsong Wang, Xilin Huang, Chunfa Liao

    Published 2024-12-01
    “…Furthermore, cathode products are analyzed through Scanning Electron Microscope (SEM), X-Ray Diffractometer (XRD), Thermal Gravimetric Analyzer (TGA), Raman Spectra and Fourier Transform Infrared (FTIR) techniques with a focus on the content and morphology of carbon elements. It was observed that the carbon content in the carbon powder produced by molten salt electrochemical method exceeded 99%, with most carbon products obtained from electrolysis in the Li-Ca chloride molten salt system being in the form of carbon nanotubes. …”
