A multi-walled carbon nanotubes coated 3D printed anode developed for Biophotovotaic applications

We report a method for the design and fabrication of 3D printed bioanodes for Biophotovotaic (BPV) applications. Electrodes were fabricated in 5 different thicknesses, from 0.2 mm to 1.0 mm with a 0.2 mm increment and the electrodes were coated with multi-wall carbon nanotubes (MWCNTs). Electrochemical characterisation of these electrodes was performed and the performance tested alongside a bare carbon paper electrode in a bespoke designed membrane electrode assembly (MEA)-type BPV device.
