Abstract:

Manganese catalysts have excellent catalytic degradation of VOCs and ozone in the field of non-thermal plasma catalysis. In this review, a comprehensive discussion of this kind of catalysts is provided from the following aspects: the synergistic effects and catalytic mechanism of manganese catalysts in the non-thermal plasma catalysis system, including changing discharge behavior, producing new active species and providing reactive sites; the common kinds of active phases, such as single metal and multi-metal catalysts; the main preparation methods: impregnation method, hydrothermal synthesis, co-precipitation method, and sol-gel method; the combination form of plasma and catalysts; the effects of manganese catalyst and energy density on the plasma catalytic degradation of toluene based on statistical analysis, the reduction of by-products of ozone and NOx; finally the perspective and future direction of manganese catalysts were proposed: manganese catalysts are still the hotspot in the field of non-thermal plasma catalysis; by the means of introducing other metal and non-metal elements, improving the dispersity of active phases, enhancing the adsorption of catalysts to further increase the catalytic activity and stability; investigating interaction mechanism between plasma and active sites of catalysts through in-situ detection technologies.
