CO₂-in-PEG emulsions were made with Pluronic 104 at different CO₂ pressure. In these emulsions, porous poly(acrylamide)s (PAM) nanoparticles around 250 nm were prepared. The nano-sized metal Ru particles were loaded on the porous PAM, which have much higher catalytic activity for benzene hydrogenation reaction compared to commercial Ru/C catalyst. More importantly, the drop size of internal phase CO₂ and the pore diameter of as-prepared PAMs can be simply tuned by changing the pressure of CO₂.
