Article.
Catalysts. vol: 10. page: .
Date: JUL. 2020.
Doi: 10.3390/catal10070753.

Abstract:
In this study, a methodology was developed for the rapid degradation of trichloroethylene (TCE) and 1,1-dichloroethylene (1,1-DCE) in distilled water and room temperature without the production of toxic chlorinated by-products. This process was carried out using bionanohybrids of different metals (Pd, Fe, Cu [read more]
