The co.(3)o_(4)nanoparticles,dominated by a catalytically active(110)lattice plane,were synthesized as a low-temperature No_(x) adsorbent to co.trol the co.d start emissions from *** nanoparticles boast a substantial quantity of active chemisorbed oxygen and lattice oxygen,which exhibited a No_(x) uptake capacity co.mensurate with Pd/SSZ-13 at 100℃.The primary No_(x) release temperature falls within a temperature range of 200-350℃,making it perfectly suitable for diesel *** characterization results demonstrate that chemisorbed oxygen facilitate nitro/nitrites intermediates formation,co.tributing to the No_(x) storage at 100℃,while the nitrites begin to deco.pose within the 150-200℃***,lattice oxygen likely beco.es involved in the activation of nitrites into more stable nitrate within this particular temperature *** co.current processes of nitrites deco.position and its co.version to nitrates results in a minimal No_(x) release between the temperatures of 150-200℃.The nitrate formed via lattice oxygen mainly induces the No_(x) to be released as No_(2) within a temperature range of 200-350℃,which is advantageous in enhancing the No_(x) activity of downstream NH_(3)-SCR catalysts,by boosting the fast SCR reaction *** to its low co.t,co.siderable No_(x) absorption capacity,and optimal release temperature,co.(3)o_(4)demonstrates potential as an effective material for passive No_(x) adsorber applications.
