Iron-based denitration catalyst and preparation method thereof

The invention provides an iron-based denitration catalyst. The catalyst comprises a carrier and a matrix, wherein the carrier comprises an oxide of zirconium and an oxide of cerium; the matrix comprises an oxide of iron and an oxide of copper; the mass ratio of the oxide of zirconium to the oxide of cerium is (1: 0.6)-(1: 0.8); based on the total mass of the carrier, the loading capacity of iron is (mass fraction) 5%-7%, the loading capacity of copper is (mass fraction) 7.5%-22%, and the mass ratio of the loading capacity of iron to the loading capacity of copper is (1: 2.5)-(1: 4). Accordingto the invention, by controlling proper component proportion and reaction conditions, the prepared catalyst has ideal specific surface area, pore volume and pore diameter, and shows an ideal catalyticeffect. 本发明提供了一种铁基脱硝催化剂，所述催化剂包括载体和基体，所述载体包括锆的氧化物和铈的氧化物，所述基体包括铁的氧化物和铜的氧化物，所述锆的氧化物与所述铈的氧化物质量比为1:0.6-1:0.8，以载体总量计，铁的负载量为（质量分数）5%-7%，铜的负载量为（质量分数）7.5%-22%，并且所述铁的负载量与铜的负载量质量比为1:2.5-1:4。本发明通过控制适宜的组分配比和反应条件，制备得到的催化剂具有理想的比表面积、孔容和孔径，表现
