In situ synthesis of CdS/CdWO₄ nanorods core-shell composite via acid dissolution.

ABSTRACT: The prevention of photocorrosion in photocatalysts allows for the use of a wide variety of visible-light-responsive photocatalysts, leading to highly efficient photocatalytic reactions. This study aimed to avoid the photocorrosion issues associated with pure CdS, a known photocorrosive photocatalyst, by forming a stable CdWO₄ shell on the surface of a CdS core. The CdS/CdWO₄ core-shell composite was formed using a unique method based on CdS elution under acidic conditions. An optimal CdWO₄ nanorod shell was formed at a pH of 0.8, a reaction time of 30 min, and a calcination temperature of 400 °C, where the core remained intact and was sufficiently coated. The prepared CdS/CdWO₄ core-shell composite was shown to be stable when exposed to light irr
