Pd nanoparticles (Pd NPs) were decorated on the designed CS/delta-FeOOH , and the resulting Pd NPs@CS/delta-FeOOH microspheres were employed as a heterogeneous catalyst in the construction of biaryl and benzonitriles. Pd NPs@CS/delta-FeOOH microspheres efficiently catalyzed the conversion of aryl iodides and bromides to the desired biaryls within 3 h. Moreover, Pd NPs@CS/delta-FeOOH microspheres showed high catalytic potential against synthesis of benzonitriles by providing yields up to of 99% within 4 h. More importantly, it was proved that Pd NPs@CS/delta-FeOOH microspheres were able to be easily recycled and reused up to eight runs for both reactions. This study reveals that Pd NPs@CS/delta-FeOOH microspheres are useful and recyclable nanocatalysts, which catalyze the synthesis of biaryl and benzonitriles with good reaction yields.eninfo:eu-repo/semantics/closedAccessChitosandelta-FeOOHPalladiumNanocatalystArticle174-12013310.1016/j.ijbiomac.2021.01.16233513423Q1WOS:000625633200013Q1
