摘要: Natural pyrite (NP) was treated using oxygen and nitrogen non-thermal plasmas to form modified catalysts. Cleaning effect of the O 2 plasma by chemical etching leads to removal of impurities from catalyst surface and sputtering effect of the N 2 plasma results in formation of pyrite nanorods. The mentioned plasmas were applied separately or in the order of first O 2 and then N 2, respectively. The catalytic performance of the plasma-modified pyrites (PMPs) is better than the NP for treatment of Reactive Blue 69 (RB69) in heterogeneous sono …
