An ideal catalyst carrier: patchy nanoparticles with dual functional domains of substrate enrichment and catalysis
CHEMICAL COMMUNICATIONS(2022)
摘要
Enriching substrates near catalysts is an effective strategy to improve heterogeneous catalytic performance. The surface of PMMA@PIL-PA patchy nanoparticles is segmented into PMMA and PIL-PA domains. The hydrophobic PMMA domain can enrich water-insoluble substrates, while the hydrophilic PIL-PA one catalyzes the reaction of water-soluble and water-insoluble substrates in close proximity. The special patchy nanoparticles with both a hydrophobic substrate warehouse and catalysis functional divisions can effectively improve the catalytic efficiency. They were employed to catalyze the acetal reaction between water-insoluble benzaldehyde and water-soluble ethylene glycol by phosphotungstic acid (PA). Compared with the homo-nanoparticles, the conversion rate was greatly improved.
