The organic pollutant hexachlorobenzene (HCB) can persist in the environment for decades, but can be completely dechlorinated within minutes to hours using palladium nanocatalysts.


Wiltschka K, Neumann L, Werheid M, Bunge M, Düring R-A, Mackenzie K, Böhm L (2020) Hydrodechlorination of hexachlorobenzene in a miniaturized nano-Pd(0) reaction system combined with the simultaneous extraction of all dechlorination products. Applied Catalysis B: Environmental 275: 119100

The respective dechlorination process could be followed in detail by solid-phase microextraction (SPME). HCB, all 11 possible intermediates, and benzene as the end product of the dechlorination process could be extracted simultaneously, regardless of their different physicochemical properties.

The results published in the journal Applied Catalysis B: Environmental present the preferred dechlorination pathway of HCB and the dechlorination performance of the nanocatalysts. The study gives an outlook on possible applications of palladium nanocatalysts for environmentally friendly technologies.
