Abstract

A facile chemical reduction approach is adopted for the synthesis of iron tungstate (FeWO₄)/ceria (CeO₂)–decorated reduced graphene oxide (rGO) nanocomposite. Surface morphological studies of rGO/FeWO₄/CeO₂ composite reveal the formation of hierarchical FeWO₄ flower–like microstructures on rGO sheets, in which the CeO₂ nanoparticles are decorated over the FeWO₄ microstructures. The distinct anodic peaks observed for the cyclic voltammograms of studied electrodes under light/dark regimes validate the electroactive proteins present in the microalgae. With the cumulative endeavors of three-dimensional FeWO₄ microstructures, phase effect between rGO sheet and FeWO₄/CeO₂, highly exposed surface area, and light harvesting property of CeO₂ nanoparticles, the relevant rGO/FeWO₄/CeO₂ nanocomposite demonstrates high power and stable biophotovoltaic energy generation compared with those of previous reports. Thus, these findings construct a distinct horizon to tailor a ternary nanocomposite with high electrochemical activity for the construction of cost-efficient and environmentally benign fuel cells.
