Hierarchical Zr-doped Fe2O3 photoanodes decorated with in situ Au nanoparticles via a surfactant-assisted one-step hydrothermal approach for efficient photoelectrochemical water splitting

The influence of CTAB and metallic Au NPs on the PEC activity of a Zr-doped Fe 2 O 3 photoanode is described. CTAB surfactant assists the in situ adsorption of Au NPs on Zr-FeOOH during hydrothermal synthesis.
