Potential Difference Driving Electron Transfer via Defective Carbon Nanotubes toward Selective Oxidation of Organic Micropollutants

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(13), P. 8464 - 8472

Published: June 10, 2020

Nanocarbon-based persulfate oxidation emerges as a promising technology for the elimination of organic micropollutants (OMPs). However, nature active site and its working mechanism remain elusive, impeding developments high-performance oxidative water treatment practice. Here, we report that defect-rich carbon nanotubes (CNTs) exhibit superior activity in activation peroxymonosulfate (PMS) OMP oxidation. Quantitative structure-activity relationship studies combined with theoretical calculations unveil double-vacancy defect on CNTs may be intrinsic site, which works conductive bridge to facilitate potential difference-dominated electron transfer from highest occupied molecular orbital OMPs lowest unoccupied PMS. Based this unique mechanism, established CNTs@PMS system achieves outstanding selectivity realizes target-oriented specific complicated aquatic environment. This work sheds new light carbocatalysis selective develops an innovative toward remediation practical wastewater.
