摘要: As a dangerous environmental pollutant, mercury is widely existed in coal-fired power plant gases. In this manuscript, a novel and reliable high-capacity adsorbent (MagFeSi-Cu°) was synthesized by powder metallurgy method to remove Hg° from flue gases. The FeSi, the nano-copper and the silica-coated magnetic Fe 3 O 4 nanoparticles were mixed and calcinated at 300° C by powder metallurgy method. Copper nanoparticles were uniformly dispersed on the FeSi surface by the linkage of Cu 3 Si, which was formed by the interfacial …
