查询词典 H2O

The results showed that the amorphous iron oxide has highly catalytic activity. The intermediate products are pyrocatechin, hydroquinone, benzoquinone and low-grade fatty acid. The mechanism of catalyst oxidation is assumed that the free radical OH attacks benzene cycle at the adjacent position and para-position of OH on phenol so that the benzene cycle is opened and low-grade fatty acid is produced and transformed into CO2 and H2O.

结果表明，非晶铁氧化物催化剂在催化氧化降解苯酚时具有较高的催化活性，苯酚降解的中间产物有：对苯二酚、邻苯二酚、苯醌和低级脂肪酸，其降解机理是羟基自由基攻击苯环上OH的部位或对位而使苯环开环，生成低级脂肪酸，并最终转化成二氧化碳和水，从而使苯酚得以降解。
