Efficient and Selective Detection of Nitroaromatic Explosives on ZnBTCA
As one of the most important chemicals that concerns the homeland security and humanitarian safety, rapid detection and discrimination of hidden explosives are always the important aspects in the entire world.However, in recent years, with the increasing levels of the preparation and hidden strategies, real-time detection of explosives faced more severe challenges.So in this aspect, establishing and developing new sensing ideas and methods for the future needs are always highly needed.Among different nitro compounds, trinitrophenol (PA) is the most common constituent to prepare powerful explosives all over the world.A few works on the detection of nitro explosives have already been reported in the past few years;however, selectivity is still in its infant stage.Herein, the metal-organic framework ZnBTCA was synthesized in a facile method and was characterized by X-ray diffraction (XRD),and N2 adsorption-desorption (BET).It was successfully applied for efficient and selective detection of nitroaromatic explosives such as PA, TNT, and 2,4-DNT in the aqueous phase.Compared to TNT and 2,4-DNT, ZnBTCA shows highly efficient and selective detection of PA for photoinduced electron transfer (PET) mechanism and its hydrogen-bond.We believe this metal-organic framework will emerge a new class of materials that could be potentially useful for selective detection, even for trace amounts of nitro explosives in water.
