Ru metal doped TiO2 nanoparticles were synthesized using a sol gel method with and without ionic liquid. Ru metal is well dispersed while utilizing ionic liquid as reaction medium for catalyst synthesis with respect to Ru–TiO2 catalyst. A TEM image for Ru–TiO2–IL catalyst reveals, stable, well dispersed and agglomeration free Ru metal doped TiO2 nanoparticles. CO2 Hydrogenation reaction on task specific ionic liquid medium, offered the formic acid in high TON/TOF value with added advantage of 5 times catalyst recycling.
