CdIn2S4/self-assembled g-C3N4 composite material with boosted photocatalytic degradation performance: The significance of morphology and structure

The influence of morphology on the photocatalytic performance of catalysts is a critical aspect that merits further exploration. This study successfully synthesized a series of CdIn 2 S 4 /self-assembled g-C 3 N 4 photocatalysts with varying morphologies and structures via an in-situ deposition approach. The unique combination of g-C 3 N 4 ′s surface curvature and the radial-spreading layers significantly contributed to the superior photocatalytic activity observed in the optimal sample. This sample achieved an impressive 91.3 % degradation of methyl orange within 30 min and an 81.6 % degradation of tetracycline hydrochloride in 120 min. These degradation rates surpassed those of pristine g-C 3 N 4 by factors of 13.12 and 1.14, respectively. The findings of this research offer a promising strategy for designing highly active heterojunction photocatalysts tailored for pollutant removal and guiding the uniform deposition of CdIn 2 S 4 .
