Microwave-assisted surface attachment of aluminium ions on in situ diluted titanium-doped hematite photoanodes for efficient photoelectrochemical water-splitting

Al/Ti co-doping was performed through an effective microwave-assisted surface attachment method. The synergistic effect of Al/Ti co-doping and an Al 2 O 3 passivation layer significantly boosts the PEC performance in the Al(5 mM)/Ti(4%):Fe 2 O 3 photoanode.
