Abstract

Abstract

Using Iron(Ⅲ) nitrate nonahydrate and calcium nitrate tetrahydrate as raw materials, deionized water as solvent, citric acid as complexing agent, ammonia water to adjust pH value of solution, blank cordierite honeycomb as support, dicalcium ferrite cordierite honeycomb support type catalyst was prepared. The results show that nanoscale dicalcium ferrite/cordierite honeycomb-supported catalyst with single phase, high crystallinity and developed porosity can be obtained when the molar amount of citric acid is 2.5 times the total amount of calcium and iron ions, and calcinated at 700 ℃ for 2 h. The as-prepared nanosized dicalcium ferrite has a specific surface area of 174.29 m²/g, pore volume of 0.31423 cm³/g, pore size of 7.31 nm, and average pore size of 1.89 nm. It is a kind of non-noble metal catalysts for methane gas (VOCs of typical sintering flue gas) with good catalytic removal and mineralization performance.
