The synthesis and characterization of two dimensional materials are in the focus nanomaterial surface science, heterogeneous catalytic nanoelectronic research laying basis for various technological applications. Hexagonal boron nitride (h-BN) is an important member 3D reduced materials. Atomically clean sp2-hybridized 2D nano-layers can be grown on metal supports by different chemical physical vapor deposition techniques. In case a significant lattice mismatch strong interaction at h-BN/metal interface, periodically undulating monolayer - so-called "moirè structure" formed. present review, we address some characteristics h-BN prepared several surfaces, its application as template individual atoms, clusters molecules. Moreover, experimental findings collected about features applications nanosheets supporting We highlight results recent science studies, which emphasize unique role including nanomeshes characteristic adsorption properties, stability activity. few layer defective involving their also subject review. comprehensive overview electronic vibrational states nanoparticles (covered adsorbates, well) monitored spectroscopy tools, e.g. XPS, ARPES, UPS, LEIS, AES, STS HREELS. elaborate structural morphological information nanoobjects obtained scanning probe microscopy (SPM).

The utilization and selectivity of single atoms have garnered significant attention among researchers. However, they are easy to agglomerate because their high surface energy. To overcome this challenge, it is crucial seek suitable carriers anchor metal achieve optimal performance. In work, the structures transition embedded in hexagonal boron nitride (MB2N2, M = Fe, Co, Ni, Cu, Zn) constructed used for adsorption sensing lithium battery thermal runaway gases (H2, CO, CO2, CH4) through DFT method. behavior MB2N2 was evaluated energy, sensitivity, recovery time. calculation results indicate that CoB2N2 exhibits strong capacity both H2 CO. sensitivity FeB2N2 toward CO as 3.232 × 1016. Subsequently, mechanism studied TDOS PDOS, showed hybridization between orbitals enhanced gas This study presents novel approaches designing single-atom developing sensors detecting gases.
