“…Furthermore, the III-V nanotubes have many advantages over CNTs because they possess high reactivity of the exterior surface, facilitating sidewall decoration and stability at high temperature (17,18). For instance, the BNNTs can intrinsically be excellent sensors for detecting some harmful gases, such as CO, NO (19), N 2 O (20), NH 3 (21), and O 2 (22). Due to the partially ionic character of III-V bonds, the III-V nanotubes also exhibit ionic properties, which could make their dispersion in water much easier than the nonionic and hydrophobic CNTs (23).…”
