Solar-microbial hybrid device based on oxygen-deficient niobium pentoxide anodes for sustainable hydrogen production.

ABSTRACT: Hydrogen gas is emerging as an attractive fuel with high energy density for the direction of energy resources in the future. Designing integrated devices based on a photoelectrochemical (PEC) cell and a microbial fuel cell (MFC) represents a promising strategy to produce hydrogen fuel at a low price. In this work, we demonstrate a new solar-microbial (PEC-MFC) hybrid device based on the oxygen-deficient Nb₂O₅ nanoporous (Nb₂O_5-x NPs) anodes for sustainable hydrogen generation without external bias for the first time. Owing to the improved conductivity and porous structure, the as-prepared Nb₂O_5-x NPs film yields a remarkable photocurrent density of 0.9 mA cm^-2 at 0.6 V (vs. SCE) in 1 M KOH aqu
