Excellent Fenton-like catalyst application in alkaline solution

Fenton process has been widely applied for environmental restoration. However, acidic and neutral solutions are always needed in order to obtain an excellent catalytic activity. Flower-like MoS 2 was firstly used as a Fenton catalyst with higher activity in alkaline solution than that in acidic and neutral ones. The catalytic mechanism indicated that [Formula: see text] and [Formula: see text] radicals formation induced the excellent catalytic activity in alkaline solution. Effects of pH, catalyst dosage, H 2 O 2 and RhB concentrations on catalytic activity were studied, and the quantitative relations were established. The experimental result demonstrated that the catalyst was stable in alkaline solution. The leaching Mo was smaller than 2[Formula: see text]mg/L.
