“…13 To control biofouling, some strategies have been studied, such as feed pretreatment, biocide application, membrane surface modication, etc. 17 However, feed pretreatment (such as coagulation or otation) has limited the application due to high expense 18 and non-persistent effects on bacteria inhibition. 19,20 Continuous application of biocides (e.g., chlorine or ozone) cannot guarantee the inhibition of biolm formation, but may be detrimental to polymer membranes and generate toxic disinfection byproducts.…”

“…Most excitingly, NCS was found to be nontoxic, easy to use, readily soluble in water, and relatively inexpensive, all of which make it a candidate for use in water treatment. 108 Generally, NCS is considered an alternative to free chlorine in the synthesis of N-halamines because it is less aggressive yet has greater activity in the presence of other contaminants. NCS is a chlorinating agent, donating chlorine (+1) to synthesize other N-halamines.…”

“…Sometimes, a Cl 2s signal at 271.4 eV can be detected. 108,157,194,263 To effectively analyze the N−X bond of organic Nhalamines, EDX has become an important tool because it can yield elemental characterization. On the basis of the elemental composition of N-halamines, 253,262,266 the existence of a N peak and a Cl peak (or a Br peak) in EDX spectra is thought to prove the generation of N-halamines.…”

“…However, there is a dearth of studies on the antibacterial properties of succinimide-containing N -halamines, possibly because of the instability of the N–X bonds in the succinimide ring. Yu and co-workers used N-chlorosuccinimide (NCS) as an antimicrobial additive in reverse osmosis (RO)-based membranes. They found that NCS effectively inactivated bacteria on the surface without damaging the RO membranes.…”

Microbial contamination arising from pathogens poses serious threats to human health and in recent decades has presented an unprecedented challenge to antibacterial research. Of the various antibacterial agents that effectively kill pathogens, halogen-based antibacterial compounds have been successful in eliminating harmful pathogen-associated diseases and are becoming the most popular disinfectants. As a significant subcategory of halogen antibacterial agents, N-halamines have drawn increasing research interest into their chemistry and practical applications. N-Halamines have many advantages over other antibacterial agents, including effectiveness against a broad spectrum of microorganisms, long-term physicochemical stability, high structural durability, and the regenerability of their functional groups, with corresponding renewal of their antibacterial properties. This review examines recent progress and research trends in both theoretical and experimental studies of N-halamines, with the aim of providing a systematic and comprehensive survey and assessment of the significant advances in our understanding of antibacterial N-halamines. This review serves as a practical guide to developing N-halamines through both broad and in-depth basic research and offers suggestions for their potential future applications.

Carbon‐Supported Au Catalyst in Acetylene Hydrochlorination: Enhancing Catalytic Performance by Complexation of Dicarbonyl Ligands

et al. 2022

Carbon-supported Au (Au/AC) has been proven to be one of the most promising catalysts in the field of acetylene hydrochlorination. However, the catalytic performance of conventional Au/AC catalyst is usually limited due to the unsatisfactory dispersion of active Au cation on the surface of the support, carbon deposition, and inevitable reduction to inactive Au nanoparticles. Herein, Au catalysts with highly dispersed Au cation were developed using the complexation of dicarbonyl ligand N-chlorosuccinimide (NCS) and N-methylsuccinimide (NMS). The obtained AuÀ NMS/AC and AuÀ NCS/AC catalysts with 0.1 wt.% Au loading possessed acetylene conversion of 98 % and 88 % at 180 °C and GHSV (C 2 H 2 ) of 160 h À 1 , which were clearly better than that of pristine Au/AC. The characterization results showed that coordination between Au cation and ligands enhanced the dispersion of Au species, suppressed the reduction of Au cation, and reduced the formation of carbon deposits. Density functional theory (DFT) calculations suggest that AuÀ NMS/AC and AuÀ NCS/AC catalysts follow a HClpreferred concerted addition reaction mechanism with lower reaction energy barrier. This favors the high activity and nuclearity stability of the Au center. This study provides great potential for the use of dicarbonyl ligands on Au-based catalysts in acetylene hydrochlorination.
