Summary: | The invention discloses an automobile exhaust treatment catalytic material which is prepared by the following method: adding zinc nitrate and tetrabutyl titanate into a DMF/ethanol mixed solvent, then adding PVP and ammonium bicarbonate, stirring and mixing uniformly, performing electrostatic spinning by taking the mixture as a spinning solution to form PVP-ZnTiO3, and then performing heat treatment in air at 350-450 DEG C to obtain hollow porous ZnTiO3 nanofiber; dissolving sodium molybdate and cobalt nitrate in a mixed solution of ethanol and glycerol, then adding trisodium citrate, placing the hollow porous ZnTiO3 nanofibers in the mixed solution, carrying out solvothermal reaction at 180-200 DEG C, and then carrying out heat treatment at 300-400 DEG C to obtain the hollow porous ZnTiO3-CoMoO4.
本申请公开了一种汽车尾气处理催化材料,采用如下方法进行制备:将硝酸锌和钛酸四丁酯加入DMF/乙醇的混合溶剂,随后加入PVP、碳酸氢铵,搅拌混合均匀,以其作为纺丝液进行静电纺丝形成PVP-ZnTiO3,随后在空气中以350-450℃进行热处理,得到中空多孔的ZnTiO3纳米纤维;将钼酸钠、硝酸钴溶于乙醇和丙三醇的混合液中,随后加入柠檬酸三钠,将中空多孔的ZnTiO3纳米纤维置于以上混合溶液,180-200℃条件下溶剂热反应,接着 |
