Hydrogen purification material as well as preparation and application thereof

The invention belongs to the field of hydrogen purification, and particularly discloses a hydrogen purification material as well as preparation and application thereof. The hydrogen purification material is a compound of copper silicate with a silicon malachite structure and an A-type molecular sieve, the content of the copper silicate with the silicon malachite structure is 30-70%, and the balance is the A-type molecular sieve. The preparation method comprises the following steps: coprecipitating a copper ammonia solution and silica sol, washing, drying and roasting to prepare copper silicate with a silicon malachite structure, compounding the copper silicate with an A-type molecular sieve, and molding. The purification material can remove trace CO, O2 and sulfur in high-purity hydrogen at the same time under the condition of 60-120 DEG C, and meets the requirements of national hydrogen standard GB/T37244-2018 for fuel cell vehicles. 本发明属氢气纯化领域，具体公开了一种氢气纯化材料及其制备和应用。所述的氢气纯化材料为硅孔雀石结构的硅酸铜和A型分子筛的复合物，其中硅孔雀石结构的硅酸铜
