采用分步酸化法制备了CR207催化剂。考察CR207对反应速率、碘离子氧化率、双氧水的利用率的影响，研究CR207是否对碘离子造成过氧化。结果表明，当n（I-）：n（H2O2）＝2：1，每0.023 mol碘离子中CR207用量为65 mg时，能够使双氧水氧化碘离子的速率提高30倍以上，10 min内氧化率提高2.73倍，反应终点时间由原来的51 h缩短至2 h。在催化双氧水氧化碘离子时CR207没有造成过氧化现象。

The catalyst CR207 was synthesized by multi -step method.The properties of the catalyst such as reaction rate, oxidation rate , and utilization of hydrogen peroxide ( H2 O2 ) and peroxidation of iodine ion were researched.The solution with 0.023 mol/L iodine ion and 0.065 g/L CR207 was prepared.Quantitative H2 O2 was poured in the solution with ration of n(I -):n(H2O2) =2:1.The results indicated that the reaction rate of iodine ion oxidized by hydrogen peroxide increased more than 30 times, the amount of oxidation product increased by 2.73 times in 10 min, the time of reaction time was shortened from 51 h to 2 h, compared to the reaction without catalyst.There was no peroxidation when excess H2 O2 was poured into the solution.
