Enhanced PEC generation of hydrogen from seawater driven by efficient and stable Ti-Fe2O3 photoanode

Incorporation of Ti4+ ions into the hematite (alpha-Fe2O3) photoanodes has garnered significant consideration for the photoelectrochemical water splitting process since it improves the charge transport and optical properties of pristine hematite material. Herein, we have approached a facile route to fabricate the thin films of Ti-Fe2O3 by spray pyrolysis treatment. The Ti-Fe2O3 photocurrent density delivers 1.34 mA/cm(2) at 1.23 V RHE in an alkaline seawater environment, showing its excellent performance for photoelectrochemical water- splitting applications. Moreover, it offers outstanding stability in seawater (0.5 M NaCl + 1 M KOH) at applied 1.23 V for 20 h and produces 21.79 mu mol/cm(2).h of hydrogen. Hence, it will hold a tremendously promising electrode within this area for efficient solar hydrogen generation.
