The objective of the present work is to report the synthesis, characterization and catalytic activity of novel zinc oxide nanoparticles (ZnONPs) functionalized with copper(II) and palladium(II) complexes of 4-hydroxybenzaldehyde thiosemicarbazone (BTSC) ligand. In the present study, as-synthesized ZnONPs and itspost-functionalized ZnONPs@Cu-BTSC and ZnONPs@Pd-BTSC were prepared and analyzed using UV-visible and FT-IR, PXRD, and SEM-EDX techniques. The X-ray diffraction pattern of ZnONPs showed intense peaks indexed to (1 0 0), (0 0 2), (1 0 1), (1 0 2), (1 1 0), (1 0 3) and (1 1 2) planes which corresponded to hexagonal wurtzite  phase of  zinc oxide (ZnO) nanoparticles. The catalytic activity of ZnONPs, ZnONPs@Cu-BTSC, and ZnONPs@Pd-BTSC in reducing 4-nitrophenol was investigated. The ZnONPs@Pd-BTSC showed higher catalytic activity compared with that of the ZnONPs@Cu-BTSC.
