ABSTRACT Layered double hydroxides (LDHs) are attractive non‐noble catalysts for overall water splitting (OWS), yet their hydrogen evolution reaction (HER) activity is often limited by suboptimal *H adsorption and a paucity of accessible sites. Herein, we introduce an oxygen‐vacancy (Ov) engineering strategy to construct ultrathin Ni‐Fe LDH nanosheets ...

ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...

阳离子絮凝剂PDA的合成与应用研究——对废纸再生造纸废水的处理(Ⅰ)
报道了用PDA处理废纸再生造纸废水的处理过程,研究了无机絮凝剂聚合氯化铝、聚合硫酸铁或有机絮凝剂PDA单独处理废水和无机絮凝剂与有机絮凝剂配合使用处理废水的效果。结果表明 :无机絮凝剂与有机絮凝剂配合使用有很好的处理效果 ;配合使用中有机絮凝剂相对分子质量较高者与阳离子度较高者相比,前者更有利于提高处理效果。对废纸再生造纸废水的处理使上清液COD去除率达74%~ 77%,透过率达92 %~ 99%,均超过作对比用的进口产品的处理效果,且下层絮体较大、坚韧、易于脱水。
