Stabilized Palladium on Amine‐Modified Nickel Nanoprism as a Bimetallic Catalyst for Organic Dyes Degradation

Abstract The degradation of organic dyes is important due to their persistent toxicity and adverse environmental impact. In this report, we present a catalytic system that utilizes nickel nanoprism‐supported low‐concentration palladium (Ni@NH 2 ‐Pd) to efficiently reduce hazardous organic dyes. This catalyst was synthesized through the amine functionalization of nickel nanoprism, followed by the incorporation of palladium species. The structural and elemental characteristics were confirmed using techniques such as scanning electron microscopy (SEM), energy‐dispersive X‐ray (EDX) mapping, transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), and X‐ray diffraction (XRD), which validated the prism‐like structure and characterized nickel, palladium, and other functional groups. Comparative studies indicated that the Ni@NH 2 ‐Pd catalyst displayed superior catalytic activity compared to individual nickel NPr, palladium, and NiPd NPr. catalysts. Additionally, the catalyst demonstrated high recyclability, maintaining its structural morphology and catalytic efficiency over multiple cycles.
