This study enhances microbial and chemical catalyses in bioelectrochemical systems (BESs) by designing and manufacturing new materials, elucidating the catalytic mechanisms, and applying them in wastewater treatment.

As a novel environmental biotechnology, BESs can be used for treating wastewater and generating power, producing value-added products, and detoxifying contaminants. However, the catalytic efficiency of the electrode reaction is low these systems.
