A facile method to enhance the performance of soil bioelectrochemical systems using in situ reduced graphene oxide

摘要

Bioelectrochemical systems offer a potential solution for the treatment of a broad variety of environmental contaminants. Unfortunately, when applied to the remediation of soil and sediments, the low electrical and hydraulic conductivities of these media limit their effective applicability in full-scale installations. Interestingly, these drawbacks may be overcome by including conductive particles within the soil porosity in order to maximize the outreach of the electrode through the contaminated medium, thereby minimizing electron- and mass-transfer limitations.
