High Degradation of Trichloroethylene in Water by Nanostructured MeNPs@CALB Biohybrid Catalysts
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 (P...

| description | 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 and Zn) obtained by enzyme–metal coordination called MeNPs@CALB, which present different metal species and nanoparticle sizes. The <b>Cu<sub>2</sub>O@CALB</b> biohybrid, which contained Cu<sub>2</sub>O nanoparticles, showed excellent catalytic performance in TCE degradation by removing 95% (>125 ppm) in 10 min using 1.5 g/L of catalyst. On the other hand, in the degradation reaction of 1,1-DCE, <b>Cu<sub>2</sub>O@CALB</b> eliminated 94% (93 ppm) in 1 min. <b>Cu<sub>2</sub>O@CALB</b> exhibited excellent stability and recyclability under sustainable conditions, maintaining its effectiveness in more than 90% for three cycles. |
