Abstract

The article delves into the development of perovskite ferroelectric KNbO3-A(Ni1/2Sn1/2)O3 for photocatalytic hydrogen production, highlighting the influence of A-site doping with elements of varying ionic radii. By synthesizing and characterizing samples with different dopants (Ba, Sr, Ca), the study examines how these modifications alter the crystal structure, bandgap, and photocatalytic performance. The results indicate that the optical bandgap is a critical factor affecting hydrogen production, with doped samples showing improved performance compared to pure KNbO3. The article provides a thorough analysis of XRD, Raman, UV-Vis, XPS, and photocatalytic hydrogen evolution data, offering valuable insights into the mechanisms behind these enhancements.
