The application belongs to the technical field of polymer composites, and particularly relates to a sprayable conductive PPE / PA material, which is composed of polyphenylene ether, polyamide, styrene-maleic anhydride copolymer, silane functionalized zinc tin oxide nanowire, boron-nitrogen co-doped reduced graphene oxide-silver hybrid nanosheet, antioxidant and ethylene bis-stearamide. The application first prepares zinc metatitanate nanowire through a hydrothermal-calcination method, and obtains silane functionalized zinc tin oxide nanowire through surface functionalization of aminopropyl triethoxysilane. Meanwhile, the boron-nitrogen co-doped reduced graphene oxide-silver hybrid nanosheet is prepared through a hydrothermal co-doping-in-situ reduction method. The modified compounds are melt blended, extruded and granulated together with polyphenylene ether, polyamide, a compatibilizer and the like, and then a coating is obtained through melt spraying and solidification. The application adopts nanowire and nanosheet to synergistically enhance the conductive network, and the filler is firmly combined with the matrix interface, so that the obtained material has good conductivity and excellent sprayability.

The application provides an electron transport layer for a perovskite solar cell, a perovskite solar cell and a preparation method thereof. The electron transport layer for the perovskite solar cell comprises an oxide layer and a zinc tin oxide layer. The oxide layer is a metal oxide layer, and the zinc tin oxide layer is deposited on one side surface of the oxide layer. The electron transport layer is formed by combining the oxide layer and the zinc tin oxide layer. The metal oxide layer can promote interface electron extraction, and the zinc tin oxide layer can guarantee high-speed electron transmission. The electron transport layer can jointly inhibit charge recombination, provide a more stable interface environment for a perovskite layer, ensure the stability of the perovskite solar cell, and improve photoelectric conversion efficiency.

This invention relates to the field of photocatalytic materials technology, and discloses a bromine-modified zinc tin oxide photocatalyst, its preparation method, and its application. The method includes dissolving L-tryptophan, SnCl4·5H2O, and Zn(Ac)2·2H2O in deionized water to obtain a first mixture; adding NaBr to the first mixture to obtain a second mixture; adding anhydrous sodium carbonate to the second mixture and then carrying out a hydrothermal reaction; and centrifuging, washing, and drying the product after the hydrothermal reaction to obtain the target catalyst. This invention introduces NaBr into the synthesis system, promoting the entry of bromine into the crystal interior, inducing lattice contraction and a reduction in interplanar spacing. This change in microstructure shortens the internal charge transport path and improves the charge separation efficiency of the photocatalyst. Combined with L-tryptophan to control the reaction rate, this ultimately enhances the photocatalytic degradation rate of volatile organic compounds.
