摘要：
In this work, pure MoO3 and MoO3/NiO nanolamellas are fabricated and their hydrogen sensing properties are investigated for the first time. Various characterization methods are applied to investigate the structural and morphological properties of bare MoO3 and MoO3/NiO nanolamellas. The gas sensing measurement demon-strated that MoO3/NiO-5MN exhibited the best hydrogen sensing capability and selectivity to hydrogen. The response of MoO3/NiO-5MN was 3.23 toward 1000 ppm hydrogen, which was nearly 1.85 times higher than that of bare MoO3 at room temperature. The enhanced gas sensing performance of MoO3/NiO is mainly due to the p-n heterojunction.
