采用静电纺丝和脉冲激光沉积相结合的方法制备了SnO 2-ZnO杂化纳米纤维。在600 ℃煅烧后，得到了具有无规网络结构的SnO 2包覆ZnO纳米纤维。纤维直径为55-80 nm，SnO 2存款层尺寸为10-15 nm。基于SnO 2-ZnO混合纳米纤维的传感器在200 ℃下对低至400 ppb水平的NO2浓度表现出非常高的气体响应。(C)2009 Elsevier B. V.保留所有权利。
SnO2-ZnO hybrid nanofibers were fabricated by combining the electrospinning and the pulsed laser deposition methods. After calcining at 600 degrees C, the nanocrystalline SnO2 coated ZnO nanofibers with a random network structure were obtained. The fiber diameter and the size of SnO2 deposit were 55-80 nm and 10-15 nm, respectively. SnO2-ZnO hybrid nanofibers-based sensor exhibited very high gas response to NO2 concentration as low as 400 ppb level at 200 degrees C. (C) 2009 Elsevier B.V. All rights reserved.
