Microbial fuel cell assisted band gap narrowed TiO2 for visible light-induced photocatalytic activities and power generation

This paper reports a simple, biogenic and green approach to obtain narrow band gap and visible light-active TiO 2 nanoparticles. Commercial white TiO 2 ( w -TiO 2 ) was treated in the cathode chamber of a Microbial Fuel Cell (MFC), which produced modified light gray TiO 2 ( g -TiO 2 ) nanoparticles....
