In this work, FeO and metal-organic framework MIL-101(Fe) composites (FeO/MIL-101(Fe)) was demonstrated to possess excellent catalytic property to directly catalyze luminol chemiluminescence without extra oxidants. We utilized FeO/MIL-101(Fe) to develop a ultra-sensitive quantitative analytical method for HO and glucose. The possible mechanism of the chemiluminescence reaction had been investigated. Under optimal conditions, the relative chemiluminescence intensity was linearly proportional to the logarithm of HO concentration in the range of 5-150nM with a limit of detection of 3.7nM (signal-to-noise ratio = 3), and glucose could be linearly detected in the range from 5 to 100nM and the detection limit was 4.9nM (signal-to-noise ratio = 3). Furthermore, the present approach was successfully applied to quantitative determination of HO in medical disinfectant and glucose in human serum samples.
在这项工作中，FeO 和金属有机骨架 MIL-101(Fe)复合材料（FeO/MIL-101(Fe)）被证明具有出色的催化性能，可以在没有额外氧化剂的情况下直接催化鲁米诺化学发光。我们利用 FeO/MIL-101(Fe) 开发了一种超灵敏的 HO 和葡萄糖定量分析方法。研究了化学发光反应的可能机制。在最佳条件下，相对化学发光强度与 HO 浓度在 5-150nM 范围内呈对数线性关系，检出限为 3.7nM（信噪比 = 3），葡萄糖可在 5-100nM 范围内线性检测，检出限为 4.9nM（信噪比 = 3）。此外，该方法成功应用于医疗消毒剂中 HO 的定量测定和人血清样品中葡萄糖的定量测定。
