The system was named as Pd NPs@ZnAl LDH-Sch, and its structure was fully authenticated with several techniques. The catalytic potential of Pd NPs@ZnAl LDH-Sch nanocatalyst was then evaluated in the aryl halide cyanations for the fabrication of various benzonitriles using K4[Fe(CN)6]. These tests indicated that Pd NPs@ZnAl LDH-Sch nanocatalyst is tolerant against various functional groups, and the desired benzonitrile products were acquired with good to high yields within 2 h. The hot filtration experiment revealed that Pd NPs@ZnAl LDH-Sch acts heterogeneously in the reactions. Because of its heterogeneous manner, Pd NPs@ZnAl LDH-Sch was readily recovered via simple filtration and reused up to 11 successive runs by protecting its stability/durability. Moreover, it was found that the synthesized Pd NPs@ZnAl LDH-Sch nanocatalyst shows a performance in the aryl halide cyanations better than other reported catalysts.eninfo:eu-repo/semantics/embargoedAccessBenzonitrileLayered Double HydroxidesNanocatalystPalladiumArticle219---10.1016/j.clay.2022.106433Q1WOS:000865879000006Q1
