Effect of zirconia on improving NOx reduction efficiency of Nd(2)Zr(2)O(7) nanostructure fabricated by a new, facile and green sonochemical approach

Here, we offer an easy and eco-friendly sonochemical pathway to fabricate Nd(2)Zr(2)O(7) nanostructures and nanocomposites with the help of Morus nigra extract as a new kind of capping agent. For the first time, the performance of Nd(2)Zr(2)O(7)-based ceramic nanostructure materials has been compared upon NO(x) abatement. Diverse kinds of techniques have been employed to specify purity and check the attributes of the fabricated Nd(2)Zr(2)O(7)-based nanostructurs by Morus nigra extract. Outcomes revealed the successful fabrication of Nd(2)Zr(2)O(7) nanostructures and nanocomposites applying Morus nigra extract through sonochemical pathway. All nanostructured samples have been fabricated through ultrasonic probe with power of 60 W (18 KHz). Further, the fabricated Nd(2)Zr(2)O(7)-based ceramic nanostructure materials can be applied as potential nanocatalysts with appropriate performance for propane-SCR-NO(x), since the conversion of NO(x) to N(2) for the best sample (Nd(2)Zr(2)O(7)-ZrO(2) nanocomposite) was 70%. In addition, in case of Nd(2)Zr(2)O(7)-ZrO(2) nanocomposite, the outlet quantity of CO as an unfavorable and unavoidable product was lower than the rest.
