Smart textiles consisting of cotton, Cu-BTC MOF and oxidized graphitic carbon nitride, g-CN-ox, nanospheres were synthesized and tested as nerve agent detoxification media and colorimetric detectors. Combining Cu-BTC and g-CN-ox resulted in a nanocomposite (MOFgCNox) of heterogeneous porosity and chemistry. Upon the deposition of MOFgCNox onto cotton textiles, a stable fabric with a supreme photocatalytic detoxification ability towards the nerve gas surrogate, dimethyl chlorophosphate, was obtained. The detoxification process was accompanied by a visible and gradual color change, which can be used for the selective detection of chemical warfare agents and for monitoring their penetration inside a protective layer. These smart textiles adsorbed almost 7 g of CWA surrogate/its detoxification products per gram of Cu. The superior performance was linked to the high dispersion of the MOF crystals on the fibers, and a specific texture promoting the availability of the active copper centers.
由棉花、铜-对苯二甲酸金属有机框架(Cu-BTC MOF)和氧化石墨相氮化碳(g-CN-ox)纳米球组成的智能纺织品被合成出来,并作为神经毒剂解毒介质和比色探测器进行了测试。将Cu-BTC和g-CN-ox结合得到了一种具有异质孔隙率和化学性质的纳米复合材料(MOFgCNox)。将MOFgCNox沉积在棉纺织品上后,得到了一种对神经毒气模拟物磷酸二甲酯具有卓越光催化解毒能力的稳定织物。解毒过程伴随着明显且逐渐的颜色变化,这可用于化学战剂的选择性检测以及监测它们在保护层内的渗透情况。这些智能纺织品每克铜可吸附近7克化学战剂模拟物及其解毒产物。其卓越性能与MOF晶体在纤维上的高度分散以及促进活性铜中心可及性的特定纹理有关。
