However, soot particles (PM) and nitrogen oxides (NO_x) coming from diesel engines are the main causes of air pollution, so it is necessary to design and prepare an effective catalyst for the simultaneous elimination of PM and NO_x. In this work, a novel 3DOM ZrTiO₄ support and a series of W_xCeMnO_δ/3DOM ZrTiO₄ catalysts (where x indicates the wt% of W) were designed and fabricated by the colloidal crystal template technique. Among the as-prepared catalysts, the W₁CeMnO_δ/3DOM ZrTiO₄ catalyst exhibits the highest NO conversion rate (52%) at the temperature of maximum CO₂ concentration (474°C) and achieves 90% Frontiers in chemistry880884https://www.ebi.ac.uk/biostudies/studies/S-EPMC9115385biostudies-literaturePreparation of 3DOM ZrTiO₄ Support, W_xCeMnO_δ/3DOM ZrTiO₄ Catalysts, and Their Catalytic Performance for the Simultaneous Removal of Soot and NO_x.PMC9115385Liu JWang RZhong CLi DSojka ZZhao ZKotarba AWei YYu XfalsePreparation of 3DOM ZrTiO₄ Support, W_xCeMnO_δ/3DOM ZrTiO₄ Catalysts, and Their Catalytic Performance for the Simultaneous Removal of Soot and NO_x.As an efficient and durable engine, a diesel engine has a broad application.
