[0028] Example 1
[0029] Preparation of ammonia gas sensor based on Cu-BTC / polypyrrole nanowire / graphene nanocomposite:
[0030] (1) Add 0.1 mol / L pyrrole, 0.1 mol / L cetyltrimethylammonium bromide, 0.1 mol / L citric acid and excess deionized water into the flask, and stir on a magnetic stirrer 3 hours;
[0031] (2) Step (1) Slowly add 20 mL of 0.5 mol / L ammonium persulfate solution to the mixed solution with a burette, continue to stir for 4 hours, filter, wash, and dry at 60°C;
[0032] (3) Take 0.5 g of the prepared polypyrrole nanowire / graphene composite material and add it to a solution containing 0.1 mol / L trimellitic acid, 0.1 mol / L copper nitrate, 20 mL DMF, 12 mL ethanol and 8 mL water for ultrasonic dispersion 1h;
[0033] (4) Transfer the solution in step (3) to the reaction kettle, cover it, and place it in an oven at 80°C for 24 hours, filter, wash, and dry to obtain Cu-BTC / polypyrrole nanowire / graphene nanocomposite , And then load it on the ITO conductive glass;
