Catalytic dechlorination of 1,2-DCA in nano Cu⁰-borohydride system: effects of Cu⁰/Cuⁿ⁺ ratio, surface poisoning, and regeneration of Cu⁰ sites.

ABSTRACT: Aqueous-phase catalyzed reduction of organic contaminants via zerovalent copper nanoparticles (nCu⁰), coupled with borohydride (hydrogen donor), has shown promising results. So far, the research on nCu⁰ as a remedial treatment has focused mainly on contaminant removal efficiencies and degradation mechanisms. Our study has examined the effects of Cu⁰/Cuⁿ⁺ ratio, surface poisoning (presence of chloride, sulfides, humic acid (HA)), and regeneration of Cu⁰ sites on catalytic dechlorination of aqueous-phase 1,2-dichloroethane (1,2-DCA) via nCu⁰-borohydride. Scanning electron microscopy confirmed the nano size and quasi-spherical shape of nCu⁰ particles. X-ray diffraction confirmed the presence of Cu⁰ and Cu<
