Nanometer Sized Tridecylamine Capped Rhodium Dispersed on High Surface Area Support: Catalytic Investigations
We report a simple procedure for the synthesis of tridecylamine (TDA) capped Rhodium (RhTDA) nanoparticles in the range of 3–10 nm supported on different supports like SBA-15, SiO2, ZrO2, Al2O3, and TiO2. These are characterized by TEM, XRD, and N2 adsorption studies. The catalytic activity of these nanometallic dispersions are tested for the liquid phase selective hydrogenation of geraniol to citronellol at 323 K under H2 pressure. The primary reaction products are citronellol and 3,7-dimethyloctanol. Analysis of the data suggests that two separate reaction paths are operative i.e., consecutive A → B → C and parallel A → B and A → C. The size of the Rhodium particle does not have a marked effect on the product distribution, however it is very much depended on the nature of support used.
