Tem Analysis

We developed a series of new hydrotalcite functionalized Ru catalytic system to synthesize formic acid via CO2 hydrogenation reaction. Advance analytical procedures like FTIR, N2 physisorption, ICP-OES, XPS, and TEM analysis were applied to understand the physiochemical nature of functionalized hydrotalcite materials. This well-analyzed system was used as catalysts for CO2 hydrogenation reaction (with and without ionic liquid medium). Ru metal containing functionalized hydrotalcite materials were found highly active catalysts for formic acid synthesis via hydrogenation reaction. The concern of catalyst stability was studied via catalysts leaching and recycling experiments. We recycled the ionic liquid mediated functionalized hydrotalcite catalytic system up to 8 runs without any significant loss of catalytic activity. Surprisingly, no sign of catalyst leaching was recorded during the catalyst recycling experiment.

A series of alumina supported Ru nanoparticles (Ru γ -Al2O3-x (x=2-10 Ru wt%) was synthesized using the ethylene glycol reduction method. XRD, TEM, EDX, H2-chemisorption, XPS and H2-TPD analytical techniques were used to understand the physiochemical nature of alumina supported Ru nanoparticles. All the well-characterized Ru#Al2O3-x (x=2-10 Ru wt%) catalysts were used for high-pressure CO2 hydrogenation to formic acid synthesis. A clear correlation was recorded between the physiochemical properties of developed catalysts and the molar quantity of formic acid. Among all the developed catalysts, Ru#Al2O3-2 catalyst with or without ionic liquid reaction medium gave a good molar quantity of formic acid. Application of ionic liquid was also expanded, and ionic liquid medium appeared as a good solvent system as compared to the amine solvent system, which not only provides better solubility of reactants and catalysts but also found useful in the easy recovery of formic acid after the completion of the reaction. The catalyst recycled seven times with easy product isolation stem to make this system very useful and fulfill the requirement of sustainable chemistry.
