Novel heterogeneous denitrification catalyst over a wide temperature range: Synergy between CeO2, ZrO2 and TiO2

The synergistic effect of CeO2, ZrO2 and TiO2 promote to form Ce3+ ions and oxygen vacancies, which contributed to the formation of chemisorbed oxygen and is beneficial to form reactive centers or yield active oxygen species in catalytic reduction of NO. Moreover, abundant acid sites, and redox capability give rise to the superior performance of the catalysts.
