采用共沉淀法合成了TiO2及TiO2-Fe2O3载体，并对硫酸氢铵与上述载体之间的相互作用及硫酸氢铵的具体分解行为进行了研究.结果表明，催化剂载体表面含硫官能团主要以双齿硫酸盐的形式存在，含氮官能团以铵根离子的形式存在.当硫酸氢铵沉积于催化剂载体表面时，由于硫酸根离子具有较强的电负性，Ti原子及Fe原子处于电子缺失状态.对于TiO2载体，硫酸根离子主要与Ti原子相连；而对于TiO2-Fe2O3载体，Ti原子及Fe原子均为硫酸根离子主要的附着位点.采用热分析方法及原位红外对硫酸氢铵在TiO2及TiO2-Fe2O3载体表面的分解行为进行了研究，发现铁氧化物的添加显著促进了硫酸氢铵在低温区间内的分解行为；与铵根离子相比，硫酸根离子具有更高的热稳定性.催化剂稳定性测试结果表明，铁氧化物的添加显著提高了低温抗硫抗水性能，为实现低温SCR技术的工业应用提供了理论基础.
