“…Wang and co-workers reported that simple aeration with MoS 2 can turn oxygen to superoxide anion radicals. 31 It is reasonable to believe that in path B the direct reduction product of O 2 is the superoxide anion radical, although more mechanistic details are being investigated in our lab.…”

Tetraethylthiuram disulfide (TETD) is one of the most important thiuram-class rubber vulcanization accelerators and a “star molecule” in other areas. The development of a mild, efficient, low-cost, safe and sustainable approach to produce TETD is extremely desirable. Here, we developed a much-improved route to synthesize TETD using MoS2 as the catalyst and ethanol as the solvent. A packed-bed microflow strategy was implemented to accelerate the catalytic process. TETD was obtained with an excellent yield and purity within a short residence time. Besides, this continuous process did not generate any waste salts, rendering it a sustainable method for producing thiuram-type compounds.

“…40 The hole interacts with the H 2 O to produce a hydroxyl radical ( OH) and a proton (H + ). 46 The electron readily combines with the molecular oxygen to form superoxide radicals and extra holes in the system translate the unconverted O 2 À to singlet oxygen. 47,48 The interference of proton (H + ) with superoxide radical yields H 2 O 2 .…”

Dye‐selective nanofiltration membranes have great potential for chemical dye separation and purification as well as dye wastewater treatment. Two‐dimensional materials such as molybdenum disulfide (MoS2) with excellent physical and chemical properties are ideal nanofiltration membrane materials. MoS2 with few layers is used in combination with polyphenols to prepare highly selective filtration nanofiltration membranes for cationic dyes. The tannic acid (TA)‐MoS2 composite material is constructed on the surface of a micro‐porous Mixed Cellulose Ester membrane by a vacuum filtration method, and the nanofiltration membrane exhibits good flexibility and excellent film‐forming properties. The maximum filtration efficiency of TAMoS2 nanocomposite film for R6G can reach 80%, while for EY and MO, it is only 9.6% and 6.1% respectively. Filtration studies on mixtures of two different types of dyes show that the composite nanofiltration membrane has excellent separation performance. The separation characteristics and mechanism of the composite nanofilm on dyes are carefully studied, showing good selectivity for cationic dyes, which can be ascribed to the synergistic effect of non‐covalent interactions and steric hindrance. This work paves the way for the use of eco‐friendly membranes for water and wastewater treatment and provides an environmentally friendly solution for various applications.
