1、fe/fes@sio2材料的形态分析 如图1所示,该图为fe/fes@sio2材料的ftir谱图。从图1可以看出,3462cm-1的宽带峰可归因于吸附水分子的伸缩振动和水化硅烷醇组的o-h。1620cm-1的波段的小峰可以归因于吸附水分子的h-o-h弯曲振动。以1062和457cm-1为中心的频带是si-o-si的伸缩振动,si-o-si是合成的介孔氧化...
FTIR analysis of the initial and reacted FeS samples has shown that during the aqueous oxidation of FeS by O2 a sulfur rich layer is formed on the mineral surface. The experimental results indicate that the protons adsorb on the mineral surface and catalyze Fe2+ release into solution (by ...
