【Abstract】Using CIKI as the research platform, this paper used topic search to analyze the publication time, quantity, subject field and research institutes of “nano-zero-valent iron” and “modified nano-zero-valent iron”. The results show that: 1. The research on nano-zero-valent iron increased fastest from 2010 to 2015, and then stabilized, with 104 articles published in 2018; 2. The related research on modified nano-zero-valent iron began in 2011, and increased fastest from 2014 to 2016; 3. The mid-term literature on nano-zero-valent iron was the largest, accounting for 56.0%. Bachelors degree thesis was the most among the literature on modified nano-zero-valent iron, accounting for 57%, journal literature only accounting for 33%. 4) Modified nano-zero-valent iron related research accounted for 17.5% of nano-zero-valent iron related research; 5. Modified nano-zero-valent iron related research covered only 52.9% of the disciplines of nano-zero-valent iron.

纳米零价铁是一种自纳米工艺技术发展成熟后开发出的反应活性强且具有强还原性的物质,广泛应用于去除二氯苯酚、三氯乙烯、多氯联苯、甲基橙等有机污染物和硒、鎘等无机污染物[1-6],也有研究表明在硝酸盐氮初始浓度为20mg/L,反应初始pH为5,温度为30℃时,纳米零价铁对硝酸盐的去除率可达83.2%[7]。据报道,纳米零价铁作为催化剂性能良好,可以用于水相硝基苯选择性催化加氢制备苯胺,并且可以保留CHO、CN、SCN等易还原的官能团[8],对烯烃、炔烃的加氢催化可以循环利用十次以上[9],以两性树脂为载体的纳米零价铁颗粒,可以不受芳香环、硝基或芳卤等官能团的影响催化芳香亚胺和醛类定量加氢[10]。改性纳米零价铁是在纳米零价铁的基础上,使用橡木、椰壳等制备的生物炭、硅藻土、沸石、碳纳米管等物质在高温、真空或惰性气体条件下反应制备而成的,使材料稳定性、还原性等性能得到增强。……
