“…It exhibits typical metallic properties, different from that of semimetallicity for graphene and semiconductivity for GD and 2D-poly-C 60 . By cutting it into nanoribbons or performing surface hydrogenation, the BPN can be made semiconducting. , Its unique atomic arrangement imparts various anisotropic properties, such as electrical conductivity (including spin current), thermal conductivity, , and mechanical anisotropy, in addition to negative differential resistance, negative thermal expansion ratio, etc. It has great application potential in conductive materials, topological superconductors, lithium storage, hydrogen storage, electrocatalytic hydrogen production and oxygen reduction, , and anticorrosion coatings .…”
