摘      要：To create an artificial structure to remarkably surpass the sensitivity,selectivity and speed of the olfaction system of animals is still a daunting ***,we propose a core-sheath pillar(CSP) architecture with a perfect synergistic interface that effectively integrates the advantages of metal-organic frameworks and metal oxides to tackle the above-mentioned *** sheath material,NH2-MIL-125,can concentrate target analyte,nitro-explosives,by 1012 times from its *** perfect band-matched synergistic interface enables the TiO2core to effectively harvest and utilize visible *** room temperature and under visible light,CSP(TiO2,NH2-MIL-125) shows an unexpected self-promoting analyte-sensing *** experimentally reached limit of detection(～0.8 ppq,hexogeon) is 103 times lower than the lowest one achieved by a sniffer dog or all sensing techniques without analyte ***,the sensor exhibits excellent selectivity against commonly existing interferences,with a short response time of 0.14 min.
