Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

Gongye shui chuli, 2001 作者从静态方面测量一些变量对亚硫酸钠除氧效果的影响,来确定适用于油田注汽锅炉除氧的最佳条件和除氧剂。若单独用硫酸钠作除氧剂,则因水中亚硫酸钠的残余量高,产生严重的酸腐蚀,而不适用作油田注汽锅炉除氧剂。根据催化机理,在弱碱条件下加入二价镍离子和二价钴离子能提高水中亚硫酸钠的反应效率,降低水中亚硫酸钠的残余量,对亚硫酸钠的除氧效果具有明显催化作用。若按处理后水样中亚硫酸钠的残余量和吨水处理费用越少越好为衡量标准,硫酸钴催化亚硫酸钠除氧剂是最适合用作油田注汽锅炉用水除氧的除氧剂。

Gongye shui chuli, 2005 煤气废水生物处理出水存在着色度、NH3-N和COD等指标超标的问题，需要进行深度处理。臭氧氧化是一种比较常用的深度处理方法，然而单独依靠臭氧氧化去除废水中的COD和NH3-N需要较高的臭氧投加量，处理成本很高。探讨了臭氧对煤气废水生物处理出水的预氧化效果及其对后续生物处理过程的强化作用。实验表明，臭氧对废水的色度去除很有效，投加<160mg/L的臭氧就可去除90%的色度，废水pH较低时色度去除效果较好;臭氧氧化对废水残留COD有一定的去除作用，不同的pH条件下去除率有差异，总体每mg臭氧可去除0 ...

Gongye shui chuli, 2013 利用臭氧氧化法处理含硫石油废水,考察了n(O3)∶n(S2-)、温度对废水中S2-去除效果的影响。实验结果表明,臭氧氧化法可以有效去除废水中的S2-。臭氧氧化包括快速氧化和慢速氧化两个阶段。提高反应温度,有利于S2-的去除,但在较高n(O3)∶n(S2-)下,快速氧化阶段硫化物的去除速率受温度的影响并不明显。
