英文摘要：

A chemo-resistive gas sensor based on the synthesized tannic acid（TA）functionalized and reduced graphene oxides（rGO）are fabricated and investigated for ammonia gas sensing at room temperature.The results show that the prepared chemo-resistive gas sensor based on tannic acid（TA）functionalized and reduced graphene oxides show excellent response performance,good reproducibility,and high selectivity for ammonia gas in contrast to the ethanol gas and acetone gas.The response and recovery time of the chemo-resistive gas sensor based on tannic acid（TA）functionalized and reduced graphene oxides are 20 sand 100srespectively for ammonia gas concentration in 6 550×10-6,and showing faster response and recovery speed for high concentration ammonia gas.
