我们研究了 Al2O3 掺杂 ZnO 在贫燃条件下燃烧控制的传感特性。使用丝网印刷技术在氧化铝基板上形成由听者、电极和传感层组成的平面型传感元件。即使在稀薄条件下，我们的废气传感器也表现出显着的电阻变化，这显然是由于本体和表面传导机制的同时起作用。利用该传感器对家用锅炉进行反馈控制，我们已经证明该系统可以在最佳燃烧条件下成功运行。
We have investigated the sensing properties of Al2O3-doped ZnO for combustion control in lean-burn conditions. Planar-type sensing elements made of hearer, electrode and sensing layer were formed on an alumina substrate using a screen-printing technique. Our exhaust-gas sensor exhibits significant resistance changes even under lean conditions, apparently due to the simultaneous functioning of bulk and surface conduction mechanisms. Utilizing the sensor for the feedback control of a domestic boiler, we have demonstrated that the system can be successfully operated at the best combustion conditions.
