Ultrasensitive and low-cost detection means for immediate recognition of peroxide explosive compounds such as triacetone triperoxide (TATP) and hexamethylene triperoxide diamine (HMTD) have attracted tremendous attention due to their great significance in home land security. Metal hydrogen bronzes are promising materials for instant detection and neutralization of hazardous peroxides. This study reports on the sustainable fabrication of colloidal molybdenum oxide MoO3 nanorods. Nanoscopic colloidal molybdenum hydrogen bronze (MHB) were evolved from synthesized MoO3 via acidic hydrothermal treatment. Colloidal MHB particles with dark blue colour demonstrated complete change in surface properties from hydrophilic to hydrophobic; they demonstrated effective phase transfer from aqueous phase to organic phase. This novel reducing agent did not only offer neutralization of hazardous peroxides but also demonstrated an instant detection of such compounds with colour disappearance. Furthermore, MHB can act as a desensitizer for different hazardous materials by shuttling reactive hydrogen ions rendering them into non-explosive compounds.

新型胶态钼氢青铜(MHB)用于即时检测和中和有害过氧化物

用于立即识别过氧化氢爆炸性化合物(如三丙酮三氧化二氢(TATP)和六亚甲基三氧化二氢二胺(HMTD))的超灵敏,低成本的检测方法,由于其在本国土地安全中的重要意义而备受关注。金属氢青铜是用于即时检测和中和有害过氧化物的有前途的材料。这项研究报告了胶体氧化钼MoO 3纳米棒的可持续制造。纳米胶体钼氢青铜(MHB)由合成的MoO 3演化而来通过酸性水热处理。深蓝色的胶体MHB颗粒表面性能从亲水性变为疏水性完全改变;他们证明了从水相到有机相的有效相转移。这种新颖的还原剂不仅可以中和有害的过氧化物,而且还可以立即检测出这种具有颜色消失的化合物。此外,MHB可以通过穿梭反应性氢离子,使它们变成非爆炸性化合物,从而对不同的有害物质起脱敏剂的作用。
