研究结果表明：采用湿法共沉淀法制备了Ag 3 PO 4 {111}/Al 2 O3纳米晶表面修饰催化剂，该催化剂具有较高的O2/H2O吸附/活化能力和光催化脱硝性能，并发现·O2-和· OH自由基在NO氧化过程中起着关键作用，原位DRIFTS研究表明NO完全矿化为硝酸盐.
HighlightsFacet engineered Ag 3 PO 4/Al 2 O 3 were fabricated via a facile wet impregnation-precipitation method.Ag 3 PO 4 {111}/Al 2 O 3 shows higher adsorption/activation of O 2/H 2 O and photocatalytic performance for NO removal.The• O 2− and• OH radicals are identified to play a critical role in NO oxidation.In-situ DRIFTS study reveals that NO is completely mineralized into nitrate.
