摘要：

Commercial molybdenum carbide (Mo2C) and ferrous iron (Fe2+) were investigated for the first time to co-catalyze the activation of H2O2 for the treatment of organic contaminants. Compared with traditional Fenton process, the presence of Mo2C decomposed hydrogen peroxide (H2O2) more effectively and accelerated the conversion of Fe3+/Fe2+. The Rhodamine B (RhB) degradation rate constant in Mo2C/Fe2+/H2O2 reached appropriately three times that in Fe2+/H2O2, and the co-catalytic reactivity of Mo2C was significantly higher than that of MoS2. In addition, (MoC)-C-2/Fe2+/H2O2 exhibited a board effect...
