- W2957723218 abstract "In the past two decades, a large number of organic sulfur compounds such as CS2 have been released into the atmosphere, which has caused some impacts on the environment. At present, most of the industrial treatment methods of CS2 have a series of problems, such as high energy consumption, the use of catalysts and additional treatment of by-products, which are not advisable from the economic point of view. Therefore, in this work, a method of efficient and rapid storage of CS2 by EDAs + EGs ionic liquid systems at room temperature and pressure without catalyst were proposed. At the same time, the change trend of temperature and conductivity of EDAs + EGs systems during CS2 storage were determined. Secondly, in order to realize the resource utilization of CS2SM, the mechanism of EDAs + EGs system storage CS2 and the properties of CS2SM were further studied by NMR, FTIR, XPS, XRD and other modern spectral techniques. The results showed that white precipitate with high melting point (127–224 °C) and high thermal stability were formed after CS2 is stored in the systems. These white precipitates had a similar chemical structure ([+H3NR1NH3+ −SC(=S)OR2(R3)O(S = )CS−]n), which were named as carbon disulfide storage material (CS2SM). Furthermore, CS2SMs were used as raw materials to one-step synthesize nano-metal sulfides (MSs) with excellent photocatalytic activity in the reduction of CO2. This provides a new method for the rapid storage and utilization of CS2, and it also has important practical significance for reducing CS2 emissions and realizing effective utilization of CS2. This efficient, green and universally applicable CS2 capture method is of great significance to reduce its hazards and obtain valuable chemicals." @default.
