In this work, novel multiporous net-like WO3 · H2O nanostructures were successfully obtained by changing the cations in a hydrothermal reaction system. The gas-sensing performance was measured by a static system. The experimental results showed that this net-like WO3 · H2O nanostructure-based sensor exhibited an enhanced response to H2S compared with that of normal WO3 · H2O nanorods. The causes of this phenomenon are discussed in detail from the two perspectives of electron transfer and gas-sensing reaction processes. We believe that this work also indicate that the net like structure is hopeful to become the ideal candidate as high performance H2S gas sensors.
