Textile wastewater, brimming with harmful organic dyes, poses a significant threat to our environment and health. Fortunately, scientists have developed a promising solution: a novel photocatalyst known as gC3N4-BC-5, coupled with peroxydisulfate (PDS). This dynamic duo boasts impressive capabilities, effectively degrading and removing dyes from wastewater.

The traditional gC3N4-BC photocatalyst faced limitations, such as restricted adsorption capacity and sluggish degradation rates. The innovative gC3N4-BC-5 composite addresses these challenges by exhibiting superior light absorption, lower energy bandgap, and enhanced separation of charge carriers. This translates to significantly improved performance: a remarkable 99.9% degradation of organic dyes, compared to 96.8% achieved by the original gC3N4-BC.

But the advancements don’t stop there. PDS integration further accelerates the degradation process, pushing the rate constant up by 50%. This dynamic duo generates potent radicals that dismantle dyes with exceptional efficiency. Moreover, the gC3N4-BC-5 composite demonstrates excellent reusability, maintaining its effectiveness for up to five cycles.

Beyond degradation, gC3N4-BC-5 excels at adsorption, removing 70.9% of dyes compared to 62.3% and 27.1% achieved by BC and pure gC3N4, respectively. This exceptional performance is attributed to favorable chemical and multilayered adsorption processes.

By coupling gC3N4-BC-5 with PDS, researchers have unlocked a powerful and sustainable approach to treating textile wastewater. This innovative photocatalyst offers exceptional efficiency, stability, and reusability, making it a promising solution for a cleaner and healthier future.
