Embodiment 1
[0060] Firstly, composite metal oxide nanomaterials are prepared as sensitive materials. In this embodiment, ZnO nanosheets are selected as sensitive materials. The specific steps for preparing sensitive materials are omitted, and no actual improvement is made here.
[0061] Then, prepare the conductance-catalysis luminescence dual-channel gas sensor, the steps are as follows:
[0062] Step 1-1-1, disperse the ZnO nanosheets in ethanol to form a suspension, and use the spin coating technology to coat the sol on the SiO2 / Si substrate with platinum microelectrodes printed on the front, and dry it in the air. Brush a layer of ruthenium paste on the back of the substrate as a heating layer, and install electrodes and thermocouples to make sensitive elements;
[0063] Step 1-1-2, place the BPCL weak luminescence analyzer at the corresponding position near the substrate, and install the sensor housing.
[0064] Finally, the conductance-catalysis-luminescence dual-channel gas detect...
Embodiment 2
[0072] First, composite metal oxide nanomaterials are prepared as sensitive materials. In this embodiment, a variety of metal oxide nanomaterials are selected to prepare six sensitive elements to form a sensor array. The specific steps for preparing sensitive materials refer to Embodiment 1.
[0073] Then, prepare the conductance-catalysis luminescence sensor array, the steps are as follows:
[0074] Step 2-1-1, disperse the various metal oxide nanomaterials prepared in the previous step in ethanol to form a suspension, and use the spin coating technology to coat the sol on six pieces of SiO2 with platinum microelectrodes printed on the front. On the / Si substrate, after drying in the air, brush a layer of ruthenium paste on the back of each substrate as a heating layer, and install electrodes and thermocouples to make multiple sensitive elements;
[0075] Step 2-1-2, install the six sensitive elements prepared in step 1 on the sensor array board as shown in Figure 3, install...
