This study reports a versatile process for the fabrication of palladium nanoparticles (Pd NPs) stabilized on Schiff base modified Unye bentonite with a coordination performance of furfural ligand (UN-Fur@PdNPs) as a promising nanocatalyst in the reduction of organic/inorganic pollutants. APTES ((3-aminopropyl)triethoxysilane)-modified UN-Fur@PdNPs has been synthesized via a facile, multi-step procedure without any additional stabilizing/reducing agents. The characterization of UN-Fur@PdNPs sample was carried out by FTIR, XRD, EDS, elemental mapping, STEM, TEM, HRTEM, and TG/DTG analyses which indicate the formation of Pd NPs (~ 10 nm) on the surface of UN-Fur. The catalytic activity/stability of the as-prepared nanocatalyst has also been assessed in the reduction of 4-nitrophenol (4-NP), Congo Red (CR), Methylene Blue (MB), and Methyl Orange (MO) dyes by NaBH4 (sodium borohydride) and chromium [Cr(VI)] by HCOOH (formic acid) in water. Catalytic efficiency retention has also been obtained after eight cycles. UN-Fur@PdNPs showed excellent catalytic performance and high stability/sustainability in the reduction of all five targeted organic/inorganic pollutants.
