Abstract
In this study, we report a photoanode consisting of a polymeric/inorganic nanojunction between novel nanostructured 3D C 3 N 4 nano-networks and BiVO 4 substrate. This nanojunction is formed such that 3D C 3 N 4 nano-networks with a positively charged surface are efficiently anchored on the BiVO 4 photoanode with a negatively charged surface. This electrostatic self-assembly can initiate and contribute to an intimate contact at the interfaces, leading to an enhanced photoelectrochemical activity and stability compared with that fabricated by non-electrostatic assembly. The C 3 N 4 nano-network/BiVO 4 photoanode achieved a remarkable photocurrent density of 4.87 mA cm −2 for water oxidation at 1.23 V (vs. reversible hydrogen electrode) after depositing FeOOH/NiOOH as oxygen-evolution co-catalyst, which is among the highest photocurrent densities reported so far for BiVO 4 -based photoanodes.
