Photocatalytic performance of novel super-hydrophilic carbon quantum dots/Fe(NO3)3 composites for catalytic applications

This study presents the development of a new carbon quantum dot/ferric nitrate (CQD/Fe(NO₃)₃) composite featuring super-hydrophilic and fluorescent characteristics tailored for efficient photocatalytic applications. The material was synthesized through a rapid microwave-assisted process using different ratios of citric acid and ferric nitrate. Structural and morphological evaluations confirmed the successful formation of uniformly distributed CQDs on Fe(NO₃)₃ flakes, with surface functional grou
