Hard carbon is promising anode for potassium-ion batteries (PIBs), however, the poor rate capability hinders its development as potential anode. To address this
汞对环境的污染引起了国内外广泛关注,而燃煤烟气排放的汞是最主要的大气汞污染源之一。钙基湿法烟气脱硫系统(Wet Flue Gas Desulfurization,WFGD)具有能协同脱除燃煤烟气中50-95%的Hg2+的潜力,但是在一定条件下,被WFGD系统捕获的Hg2+又会被还原为Hg0,导致WFGD脱汞效率降低,造成二次污染。这一现象成为当前利用已有烟气净化装置协同净化汞污染控制的突出难点问题
