Highly dispersed small Pd nanoparticles on porous P-doped carbon nanospheres for efficient CO2 fixation into cyclic carbonates under solvent-free conditions

In this study, we report a successful strategy for the generation of palladium nanoparticles on porous P-doped carbon spheres with a high surface area. The synthesized Pd/P-CS was used in the CO2 fixation reaction with various epoxides under solvent-free conditions. The prepared Pd-0/P-CS nanocatalyst was affirmed by different analysis, including TEM, FE-SEM, EDS, BET, FT-IR, XRD, and ICP-OES. The aforesaid nanocatalyst with a unique porous structure was an outstanding catalytic performance on different substrates toward produce of cyclic carbonates under solvent-free condition with high yields of final products. The catalytic activity of Pd-0/P-Cs could be maintained efficiently after recycling up to five consecutive runs under the optimized reaction conditions.
