Study of kinetics of photocatalysis, bacterial inactivation and • OH scavenging activity of electrochemically synthesized Se 4+ doped ZnS nanoparticles

High-efficient photocatalytic treatment of dye and anti-bacterial activity via electrochemically synthesized SeS2nanoparticles

“…[11,12] Semiconductor SeS 2 nano photocatalyst can use the available source of ultraviolet (UV) radiation from sunlight or artificial light and conduct a chemical reaction to degrade the organic pollutant present in both the liquid and gaseous phases. [13][14][15] However, the need for UV radiation in photodegradation processes has limited both the practicality and environmental benefits on industrially relevant scales. Hence, the present work focuses on a low-cost electrochemical technique for the synthesis of SeS 2 nanoparticles, study the kinetics of photodegradation of indigo carmine (IC) dye, optical and anti-bacterial properties of the synthesized SeS 2 nanoparticle.…”

Facile synthesis of MOF 235 and its superior photocatalytic capability under visible light irradiation

“…[4][5][6][7][8] Among various chemical, physical, and biological technologies in pollution control, photocatalysis has consistently drawn much attention worldwide since it provides the possibility to employ sunlight, which is the most attractive and abundant renewable energy, to promote reactions under very mild conditions. [9][10][11][12] Since the demonstration of the rst articial photocatalytic system for organic pollutants degradation over TiO 2 under UV light, several UV-active and visible-response photocatalysts, such as ZnO, 13,14 Fe 2 O 3 , 15,16 CdS 17,18 and ZnS 19,20 have demonstrated efficiency in degrading a wide range of organic pollutants into biodegradable or less toxic organic compounds, even eventually mineralizing them into innocuous CO 2 and H 2 O in the gas or aqueous phase. Unfortunately, the low quantum yield and solar energy conversion efficiency of these inorganic photocatalysts limit their practical applications in environmental purication.…”

Antibacterial activity of novel Cu2ZnSnS4 nanoparticles against pathogenic strains

“…), and hydrogen peroxide (H 2 O 2 ) from the nanoparticles surface which can severely damage the proteins, lipids, and DNA in the cell membrane, leading to the leakage and breakdown of the bacterial cell membrane. 11,30,31 Although there are hardly any reports on the antibacterial activity of CZTS nanoparticles favoring any of the aforementioned paradigms the possible mechanism of antibacterial action in CZTS can be explained based on the electrostatic interaction due to the opposite surface charges. 17 pH has a signicant impact on the electrical charge on the surface of the nanoparticles, and also it is well known that bacterial cell wall is negatively charged.…”
