Abstract The persistent threats posed by toxic chemical warfare agents (CWAs) such as mustard gas (bis(2‐chloroethyl) sulfide, HD) and bacterial contaminants demand the development of innovative, sustainable mitigation strategies. Photocatalytic processes that generate reactive oxygen species (ROS) offer a promising dual‐functional approach for both detoxification antibacterial defense. In this study, two structurally analogous covalent organic frameworks (COFs), BPY‐COF BD‐COF, are synthesized using benzotrithiophene donor unit paired with bipyridine biphenyl, respectively. These COFs exhibit high crystallinity, broad‐spectrum light absorption, efficient charge carrier transport, demonstrating superior performance due to incorporation heteroatoms. achieved ultrafast simulant 2‐chloroethyl ethyl sulfide (CEES) half‐life 35 min 100% selectivity sulfoxide (CEESO) under white LED light, outperforming BD‐COF. Additionally, electrospun composite fibers containing 40 wt.% maintained comparable CEES degradation rates exhibited over 99% efficiency against Escherichia coli Bacillus subtilis within 60 min. findings highlight potential multifunctional photocatalyst integrated applications in defense, addressing critical challenges public health safety.

Antibacterial and Anticorrosive Hydrogel Coating Based on Complementary Functions of Sodium Alginate and g-C3N4

Molecules, Journal Year: 2024, Volume and Issue: 29(17), P. 4192 - 4192

Published: Sept. 4, 2024

Graphitic carbon nitride (g-C3N4, CN) has emerged as a promising photocatalytic material due to its inherent stability, antibacterial properties, and eco-friendliness. However, tendency aggregate limited dispersion hinder efficacy in practical applications. To address these limitations, this study focuses on developing composite hydrogel coating, which sodium alginate (SA) molecules interact electrostatically through hydrogen bonding anchor CN, thereby significantly improving dispersion. The optimal CN loading of 35% results with tensile strength 120 MPa an rate 99.87% within 6 h. enhanced mechanical properties are attributed between the -NH2 groups -OH SA, while SA facilitate attraction photogenerated holes from promoting carrier transfer separation, strengthening action. Moreover, coating exhibits excellent corrosion resistance capabilities against Pseudomonas aeruginosa 316L stainless steel (316L SS), laying foundation for advanced antimicrobial anticorrosion systems.
