文摘

Novel Li- and Na-doped CuO nanowires and nanobelts were synthesized. Optical band gaps of CuO 1D nanostructures were systematically adjusted. Electrical conductivities of CuO 1D nanostructures were significantly improved. Low-concentration gas sensing at room-temperature were remarkably enhanced. A Mulliken charge-related mechanism was proposed to explain the unusual sensing enhancement.
