Effect of zirconia on improving NOx reduction efficiency of Nd2Zr2O7 nanostructure fabricated by a new,facile and green sonochemical approach

Here, we offer an easy and eco-friendly sonochemical pathway to fabricate Nd₂Zr₂O₇ nanostructures and nanocomposites with the help of Morus nigra extract as a new kind of capping agent. For the first time, the performance of Nd₂Zr₂O₇-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 Nd₂Zr₂O₇-based nanostructurs by Morus nigra extract. Outcomes revealed the successful fabrication of Nd₂Zr₂O₇ 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 Nd₂Zr₂O₇-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 N₂ for the best sample (Nd₂Zr₂O₇-ZrO₂ nanocomposite) was 70%. In addition, in case of Nd₂Zr₂O₇-ZrO₂ nanocomposite, the outlet quantity of CO as an unfavorable and unavoidable product was lower than the rest.
