证明了使用沸石作为改善半导体金属氧化物气体传感器响应于不同测试气体的选择性的方法的有效性。丝网印刷三氧化钨（WO 3）厚膜覆盖的氢型四种类型的沸石进行了测试，以不同浓度的NO2。乙醇和CO的传感结果被证明是可再现的气体特定的增强和减弱的响应，这表明，一个阵列的高度区分复合金属氧化物-沸石传感器可以产生电子鼻应用。©电化学学会。
The effectiveness of using zeolites as a method of improving selectivity in semiconducting metal oxide gas sensor responses to different test gases is demonstrated. Screen printed tungsten irioxide (WO3) thick films overlaid with the hydrogen form of four types of zeolites were tested to different concentrations of NO2. ethanol and CO. The sensing results were shown to be reproducible with gas specific enhanced and diminished responses, which indicate that an array of highly discriminating composite metal oxide-zeolite sensors could be produced for electronic nose applications. ©The Electrochemical Society.
