Magnetron Sputtered Al Co-Doped with Zr-Fe2O3 Photoanode with Fortuitous Al2O3 Passivation Layer to Lower the Onset Potential for Photoelectrochemical Solar Water Splitting

“…This enhanced charge carrier density has the potential to improve the PEC performance by elevating the Fermi level. This results in more band bending, which improves the electric field in the space charge layer, hence decreasing electron-hole recombination [34]. It also accelerates the electrical conductivity of the photoanode, thereby enhancing the charge transport properties within the photoanode.…”

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

“…In addition, an increase in donor density can elevate the Fermi energy toward the conduction band, causing large band bending at the photoelectrode/electrolyte interface and facilitating the rapid separation and transfer process of charge carriers, ultimately leading to a higher photocurrent. 38 Moreover, we computed the bulk and surface charge separation efficiencies of Zr-HT, Zr-HT/CTAB and Zr-HT/CTAB/Au photoanodes using 1 M NaOH and a 0.5 M H 2 O 2 hole scavenger as an electrolyte (Fig. S10 †).…”

A dual photocarrier separation channel in CdS/ZnS for outstanding photocatalytic hydrogen evolution

“…3 Therefore, photocatalytic overall water splitting (OWS) has become a popular research topic. 4,5 However, the solar-tohydrogen (STH) efficiencies obtained with the research efforts were below 10% 6 due to high water oxidation potential (1.23 V versus NHE), sluggish oxygen evolution reaction (OER) kinetics, [7][8][9] the backward reaction of dissolved H 2 and O 2 , and the side reaction of dissolved O 2 (e.g., the formation of O 2…”
