摘要：

The gas sensing properties of graphene-like nano-sheets deposited on 36 degrees YX lithium tantalate (LiTaO3) surface acoustic wave (SAW) transducers are reported. The thin graphene-like nano-sheets were produced via the reduction of graphite oxide which was deposited on SAW interdigitated transducers (IDTs). Their sensing performance was assessed towards hydrogen (H-2) and carbon monoxide (CO) in a synthetic air carrier gas at room temperature (25 degrees C) and 40 degrees C. Raman and X-ray photoelectron spectroscopy (XPS) revealed that the deposited graphite oxide (GO) was not completely reduced creating small, graphitic nanocrystals similar to 2.7 nm in size.
