In this work, we report the synthesis of Pd-based ternary Pd@CdS@TiO 2 nanocomposites using molecular precursors. This method is facile, less time-consuming, and cost-effective. This catalyst is prepared within 2 h by a solvothermal route using molecular precursors. Information about the phase, morphologies, elemental mapping, and composition of the nanocomposites was obtained using various characterization techniques. The catalytic activity of the as-prepared Pd-based ternary Pd@CdS@TiO 2 nanocomposites exhibits effective reduction efficiency for the conversion of toxic Cr(VI) to Cr(III) using formic acid as a reducing agent within 5–7 min. To the best of our knowledge, this is the first report on Pd-based ternary Pd@CdS@TiO 2 nanocomposites prepared by a solvothermal route and used as catalysts toward the reduction of hexavalent chromium at room temperature.

“…In the present work, the synthesis of ternary heterogeneous nanocatalyst (CdS–TiO 2 /Pd) was carried out by two-step solvothermal route. The use of solvothermal method for the synthesis of bare nanoparticles as well as binary and ternary nanocomposites has been reported in the literature by various researchers. − Further, it has been used for the reduction of nitroaromatic derivatives to respective amines at room temperature (RT) using NaBH 4 as a reducing agent.…”

In this study, bare CdS nanoparticles (NPs) were prepared by solvothermal method using CdCl2(3-methylbenzaldehyde thiosemicarbazone)2 as a single-source molecular precursor in the presence of ethylene glycol. Further, these CdS NPs were used for the preparation of binary (CdS–TiO2) and ternary (CdS–TiO2/Pd) heterogeneous nanocatalysts. Characterization of the as-prepared nanocatalysts has been carried out using different techniques such as powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), UV–visible diffuse reflectance spectroscopy, and photoluminescence studies. The peak observed at 2θ = 39.5° in XRD confirms the successful doping of noble metal (Pd) on the surface of CdS–TiO2 nanocatalyst, which is well supported by Raman analysis. From FESEM and TEM analyses, mixed morphology has been observed and elemental composition was confirmed by energy-dispersive X-ray spectroscopy elemental mapping. Furthermore, the as-prepared bare CdS NPs, binary CdS–TiO2, and ternary CdS–TiO2/Pd heterogeneous nanocatalysts were used for the reductive transformation of various nitroaromatic compounds to their corresponding aromatic amines at room temperature. It has been observed that among all of the catalysts, ternary CdS–TiO2/Pd heterogeneous nanocatalyst has excellent catalytic property to reduce all nitroaromatic compounds in very short time span.
