Abstract: As a common gas sensitive material,semiconductor metal oxide can be used as sensitive material to design gas sensors with different sensing principles.However,poor selectivity and sensitivity are always the shortcomings of this kind of gas sensors.In order to solve this problem,gas sensitive materials are often compounded with zeolite to prepare metal oxide/zeolite gas sensors,and improve the gas sensing characteristics of metal oxides with unique physical and chemical characteristics of the zeolite.In recent years,many researchers have studied the metal oxide/zeolite gas sensor,and the selectivity and sensitivity of this kind of sensor to target gas have been improved.In order to better summarize the existing research,focusing on the detection principle of gas sensors,this study concluded the metal oxide/zeolite gas sensors in combination with concluding the improvement of gas sensing characteristics by the zeolite,made a detailed arrangement and analysis from perspective of preparation method,gas sensing characteristics and sensitive mechanism of sensors,which provided a basis for the subsequent development of such work.

Key words: zeolite, gas sensor, selectivity, adsorption, catalysis
