30 cze 2024 · This review synthesizes recent research findings on the advancement in ZnO-based photocatalysts for water treatment, encompassing synthesis methods, structure modifications for photocatalytic efficiency enhancement, toxicity assessments, and applications in diverse water treatment processes.
27 sty 2023 · Therefore, we investigated the recent advances in zinc systems aimed at treating contaminated water and their direct application in environmental remediation.
14 paź 2024 · Several studies have indicated that ZnO nanostructures could exert biocidal action on B. subtilis and the microbial toxicity is more pronounced in the presence of light because of reactive oxygen species (ROS)-mediated effect through photo-assisted reaction. 177,178 Among all, •OH is the most reactive oxygen radical that can reacts with the ...
1 wrz 2022 · Therefore, we systematically investigated the transformation properties of ZnO NPs in sulfur-containing water and its impact on the toxicity to microalgae. The results showed that the transformation products of ZnO NPs mainly contained ZnS nanoparticles, and their contents increased with the increase of sulfur-zinc molar ratio in the aqueous ...
10 lut 2017 · In the sulfidation roasting, the objective of preheating at 400 °C is to convert elemental sulfur into zinc and iron sulfides as much as possible for reducing sulfur loss by evaporation.
22 cze 2018 · Pyrite instead of sulfur as the sulfidizing agent can not only relieve the volatilization loss of sulfur but also enhance the formation of liquid phase and thus facilitate the growth of ZnS...
1 lut 2024 · This innovative strategy harnessed the advantages of water-miscible organic/water co-solvents and polar catalysts to effectively suppress water-induced side reactions and corrosion. Additionally, G 4 's presence inhibited dendrite formation and facilitated the kinetics of sulfur conversion.
