The photocathodic properties of a Pb(Zr0.2Ti0.8)O3 wrapped CaFe2O4 layer on ITO coated quartz for water splitting.

Pb(Zr0.2Ti0.8)O3 wrapped CaFe2O4 particles were constructed on ITO coated quartz as a photocathode for efficient water splitting. A photocurrent of 152 μA cm−2 was obtained under zero bias vs. Ag/AgCl and 100 mW cm−2 with the assistance of positive poling and Ag decoration. [ABSTRACT FROM AUTHOR]
