Embodiment 1
[0034] A preparation method of a porous platinum oxide catalyst, comprising the steps of:
[0035] Step 1, adding platinum chloride into distilled water and stirring evenly to obtain a platinum ion solution;
[0036] Step 2, adding aluminum chloride to the platinum ion solution, stirring continuously until it is completely dissolved, then slowly adding high-substituted hydroxypropyl cellulose, and stirring evenly to obtain a platinum-aluminum dispersion;
[0037] Step 3, adopting a sealed reflux method to circulate ammonia gas until no more precipitation occurs, and a suspension dispersion is obtained;
[0038] Step 4, subjecting the suspended dispersion to a reaction of vacuum distillation for 2 hours, cooling to obtain a viscous liquid, and then adding it to a mold for constant temperature and pressure solidification reaction for 2 hours to obtain a mixed solid;
[0039] Step 5, immersing the mixed solid in distilled water and stirring at low temperature for 2 hours to remo...
