WebThe S 2p spectra (Figure 3d) of MoS 2 nanosheets in the S 2− oxidation state exhibit a peak at 162.4 eV and broaden toward higher BEs. Because each MoS 2 sheet has a low grafting density and a restricted number of lamellae, the S 2p spectra produced a weak signal that could not be resolved in S 2p2/3 and 2p1/2 orbits-based peaks [27,28]. WebJan 1, 2024 · While the crystal structure and physical properties of hexagonal boron nitride (h-BN) are similar to those of graphite, h-BN shows distinctly higher oxidation resistance than graphite. In addition, h-BN can form B 2 O 3 with low melting point and viscosity, which can fill pores and cracks and achieve self-healing effect during oxidation.
