The use of robust solar energy-driven photocatalysis materials to address the global energy and environmental crisis has gained significant attention in recent years.

This research aims to know how the concentration variation of cation and anion precursors in the SILAR technique affects the optical and photoelectrochemical properties of the resulting composite materials. Bi₂S₃ serves as a modifier for TiO₂ nanotube arrays (NTAs).
