Abstract

The present invention relates to a field of control of nitrogen oxide pollution, and involves a high-efficient catalyst for denitration at low temperature and preparation method thereof, which comprises the steps: (1) preparing aqueous solution of cerium nitrate; (2) soaking mesoporous silica materials SBA-15 with aqueous solution from step (1), after stirring, filtrating, washing and drying; (3) calcining materials from step (2) to obtain evenly dispersed CeO-SBA-15 materials; (4) preparing ethanol solution of manganese nitrate; (5) soaking CeO-SBA-15 materials from step (3) with ethanol solution of manganese nitrate from step (4) and volatilizing ethanol, washing and drying; (6) calcining materials from step (5) to obtain evenly distributed MnO/CeO-SBA-15 catalyst for denitration; The preparation method has simple process with lower cost, and the obtained MnO/CeO-SBA-15 catalyst has uniform and ordered pores, large specific area, narrow pore size distribution, well dispersity of catalytic components, high catalytic activity, better effect of denitration at low temperature range and wider temperature range available for denitration.
