Hyper-crosslinked Organic Polymer based Catalytic Materials: Sulfonic Acid Functionality and Nano-confinement Effect |
| 초록 |
Porous hyper-crosslinked polymers (HCPs) based novel metal-free heterogeneous solid acid catalysts were synthesized via Friedel–Crafts alkylation by self-condensation of hydroxymethyl monomers, followed by post-sulfonation process. The obtained HCP-based solid acids possessed large amounts of acidic sites with homogeneous dispersion over the large surface area of around 1000 m2g−1, and narrow dispersed pores mostly centered at about 2 nm, the junction region of micro and mesoporous. Assessed in the esterification and transesterification reactions, the obtained HCP-based porous solid acid catalysts demonstrated superior performance and special nano-confinement effect to generate biofuel products. This may offer an efficient strategy to fabricate hybrid solid acid catalysts for green chemical processes, and give the hope to prepare multi-functional catalysts from HCP-based materials. |
