From 0-dimension to 1-dimensions: Au nanocrystals as versatile plasmonic photocatalyst for broadband light induced RAFT polymerization

Abstract

Au Nanocrystals were recognized to be unprecedented photocatalyst owing to the strong localized surface plasmon resonance (LSPR). Here we exploited Au nanocrystals as plasmonic photocatalysts for photo-regulated reversible addition–fragmentation chain-transfer...

Dimensional Optimization for ZnO-Based Mechano-ATRP with Extraordinary Activity

“…Ultrasound-mediated polymerization could obviously reduce the polymerization time and temperature, , which was believed to be an attractive alternative toward conventional polymerization. Compared with photomediation, the ultrasound-generated free radicals based on piezocatalysts are usually formed uniformly throughout the reaction system, avoiding the concentration gradients caused by the attenuation of light penetration . Specifically, piezoelectric ZnO nanoparticles (NPs) − and barium titanate (BTO) NPs , are able to achieve a mechanically induced electron transfer process and promote the mechano-induced polymerization.…”

Dual enhancement of carrier generation and migration on Au/g-C3N4photocatalysts for highly-efficient broadband PET-RAFT polymerization

“…Our work has reported that Au NPs alone could catalyze PET-RAFT polymerization under visible or nearinfrared light. 29 But the conversion of the monomer after 30 h was still less than 30%, due to the short lifetime of the excited intraband transition. 30 An alternative solution to such a problem is the combination of Au NPs and semiconductors to form heterojunction-based photocatalysts.…”
