掺硼金刚石电极电化学处理二甲基亚砜工业废水

Gongye shui chuli
掺硼金刚石（Boron-doped diamond，BDD）作为高性能的电化学阳极材料，在废水中难降解有机物的矿化处理领域有广泛的应用。以BDD为阳极材料，探究电化学处理未加盐/加盐二甲基亚砜（DMSO）工业废水的效能与污染物去除机制。结果表明，未添加盐时，BDD阳极能够有效去除DMSO和COD，在电流密度3.33~23.33 mA/cm2下反应120 min，去除率分别超过90.43%和62.35%。反应过程中仅检测到微量的活性自由基，DMSO和COD的去除以直接氧化为主 ...

硫掺杂石墨烯阴极在微生物燃料电池中的性能研究

Gongye shui chuli
通过水热法将硫原子掺杂到石墨烯结构中，利用单室反应器装置搭建微生物燃料电池（MFC）。采用硫掺杂石墨烯（S-rGO）、活性炭（AC）和炭黑（CB）作为阴极催化剂，选用不同的比例进行混合。发现m（AC）∶m（CB）∶m（S-rGO）为1∶0.25∶0.075时，MFC反应器表现出最佳性能，最大输出电压为295 mV，功率密度为256 mW/cm²。此外，S-rGO的极限电流密度为3.46 mA/cm²，高于rGO（3.22 mA/cm²），表明S-rGO具有优异的电化学性能和稳定性。应对有机物冲击方面，S-
