Here, we offer an easy and eco-friendly sonochemical pathway to fabricate NdZrO nanostructures and nanocomposites with the help of Morus nigra extract as a new kind of capping agent. For the first time, the performance of NdZrO-based ceramic nanostructure materials has been compared upon NO abatement. Diverse kinds of techniques have been employed to specify purity and check the attributes of the fabricated NdZrO-based nanostructurs by Morus nigra extract. Outcomes revealed the successful fabrication of NdZrO 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 NdZrO-based ceramic nanostructure materials can be applied as potential nanocatalysts with appropriate performance for propane-SCR-NO, since the conversion of NO to N for the best sample (NdZrO-ZrO nanocomposite) was 70%. In addition, in case of NdZrO-ZrO nanocomposite, the outlet quantity of CO as an unfavorable and unavoidable product was lower than the rest.
在这里，我们提供了一种简单且环保的超声化学途径，利用黑桑提取物作为一种新型的封端剂来制备 NdZrO 纳米结构和纳米复合材料。我们首次比较了基于 NdZrO 的陶瓷纳米结构材料在脱硝方面的性能。我们采用了多种技术来确定所制备的基于 NdZrO 的纳米结构的纯度和特性，这些纳米结构是通过黑桑提取物制备的。结果表明，通过超声化学途径成功地制备了 NdZrO 纳米结构和纳米复合材料。所有纳米结构样品都是通过功率为 60 W（18 kHz）的超声探针制备的。此外，所制备的基于 NdZrO 的陶瓷纳米结构材料可以作为丙烷-SCR-NO 的潜在纳米催化剂使用，因为最佳样品（NdZrO-ZrO 纳米复合材料）的 NO 转化率为 70%。此外，在 NdZrO-ZrO 纳米复合材料的情况下，作为不利和不可避免产物的 CO 的出口量低于其他产物。
