The electronic properties of armchair (5,5) beryllium oxide nanotube (BeONT), zigzag (10,0) BeONT, and their surfaces doped by the selected elements of periods 2 (B, C, and N), 3 (Mg, Al, Si, P, and S), and 4 (Ca, Ga, Ge, As, and Se), and their hydrogen molecule adsorptions were studied using periodic density functional theory-D method. The C^(O)- and Ge^(O)-(5,5) BeONTs, C^(O)-, Si^(O)-, and Ge^(O)-(10,0) BeONTs were suggested to be new hydrogen molecule sensing materials based on the electrical resistivity measurement. The C^(O)-, Si^(O)-, and Ge^(O)-doped (5,5) BeONTs, and C^(O)- and Si^(O)-doped (10,0) BeONTs were suggested to be utilized as hydrogen storage materials.
