This facile method is time saving and low energy consuming. A facile approach is proposed to improve thermal oxidative stability of GO paper by in situ phosphorus doping during flame exposure. Then fire-alarm system is designed based on the high-temperature thermal reduction characteristic of GO. The GO paper functionalized with PTA (GO-PTA) can provide ultrasensitive, reliable and longtime fire early-warning signal. Fire alarm can be triggered at approximately 0.50 s when GO-PTA samples are attacked by fire. Phosphorus atoms are in situ doped into graphene layers during fire exposure, endowing GO-PTA paper with outstanding thermal oxidative stability, and thus alarm duration time of GO is greatly improved. The work develops advanced fire detection and early-warning sensors that provide reliable and continuous signals, which provide more available time for fire evacuation.An organic/inorganic core-shell nanobelt, TiO2@V2O5-Polypyrrole (PPy) exhibiting high photocatalytic performance and water-stability was successfully prepared. The heterojunction between the TiO2 nanobelt and V2O5 nanosheets improves both the ability to absorb visible light and the separation efficiency of the photogenerated carrier. When covered with the conjugated polymer PPy, the organic/inorganic nanocomposite absorbs throughout the whole visible light region and exhibits enhanced photocatalytic performance. Due to the outstanding transfer and separation efficiency of the electrons and holes, the new catalytic system is applied to remove water-soluble organic pollutants such as tetracycline (TC), doxycycline and oxytetracycline in high efficiency under visib
